Well, the 'acid and base story' could be about many things. It might be about their chemical properties. Acids taste sour and can react with metals, while bases taste bitter and feel slippery. For example, lemon juice is an acid and soap is a base.
Actually, a science enthusiast who has studied acids and bases in depth can also tell the 'acid and base story' well. They might have a unique perspective and can present it in an interesting way, perhaps by relating it to everyday life situations. For example, they can talk about how acids and bases are involved in cleaning products we use at home.

Blue Moon was also a good choice, with a ph between 5.5 and 6.0. In addition, Tide was also recommended as one of the most cost-effective laundry cleaners. When choosing a washing liquid, you can pay attention to factors such as the type of washing, composition, and suitable population.
You can find the price and picture of the sink. According to the information in document [2] and document [7], the price of the sink was between 70 yuan and 108 yuan, depending on the brand and model. However, because the pictures in the search results could not be provided, they could not provide pictures of the dishwashing basin.
The main components of the dishwashing liquid included a fatty alcohol ether, a foaming agent, a dissolving agent, a fragrance, water, a coloring agent, a antiseptic, and so on. Alkyl Sulfonate and Fatty Alcohol Sulphate were both anionic-type surface active agents used to remove stains and grease. Other ingredients such as straight-chain alkylbenz sulfonate had good detersive and solidifying power, and had good hard water resistance and foaming power. It was a green surface active agent. The formula for making dishwashing liquid could be adjusted according to different needs. Commonly used raw materials included basic substances such as soda, soda ash, and so on. The specific formula and production method could be chosen and adjusted according to individual needs and actual circumstances.
Jiajiayi Lemon Dishwashing Liquid was a high-efficiency oil-removing dishwashing liquid product. It contains the essence of lemon plants, which gently protects the skin and does not hurt the hands. In addition, Jiajiayi Lemon Dishwashing Liquid also added herbal suppressive ingredients, which could effectively suppress bacteria that could not be seen by the naked eye. It had the fragrance of lemon and could exert a strong oil removal effect in cold water. In addition, Jiajiayi Lemon Dishwashing Liquid could also effectively clean the residual pesticide on the surface of vegetables and watermelons. It was non-phosphorous, environmental friendly, safe and healthy. Jiajiayi Lemon Dishwashing Liquid had different specifications and packaging forms to choose from, suitable for household use.
Fruit and vegetable garden dishwashing liquid was a kind of cleaning agent suitable for cleaning fruits, vegetables and tableware. There were many sales channels and product specifications for the vegetable and fruit garden dishwashing liquid on Jingdong. The vegetable and fruit garden dishwashing liquid was known as natural, mild, and environmental friendly. It had the functions of removing oil and pesticide residue. However, the search results did not provide detailed information or user reviews about the vegetable garden dishwashing liquid. Therefore, it was impossible to make an accurate evaluation of the performance, quality, or reputation of the vegetable and fruit garden dishwashing liquid.
There were many ways to formulate and produce bulk dishwashing liquid. Among them, a traditional method was to use fatty alcohol poloxyether sulfuric acid, sulfuric acid, flake soda, coconut oil fatty acid dialcoholamid, 638, salt, essence, antiseptic, and water to formulate the formula. This formula could reach the national standard formula when the net active substance content reached 15%. In addition, there were some improvements that could reduce costs, improve thickening, increase oil removal, increase foaming ability, and improve clarity. However, the specific formula ratio and production technology needed to be adjusted according to the actual situation.
There were many recipes and production methods for dishwashing liquid. We can get the following information:
The basic formula of the dishwashing liquid included the components such as a surfacing agent, a dissolving agent, and an auxiliary agent. The common surface active agents were: Dodecylsulfuric acid, Dodecylpolyethylethylether sulfuric acid, Dodecyltrimonium chlorideand so on. The commonly used liquids were: The auxiliary agents include chelators, thickeners, stabilizing agents, preserving agents, and the like.
The method of making the dishwashing liquid included the steps of preparing the materials, preparing the solution, adding the solid raw materials, mixing them evenly, cooling and demoulding. First, he had to prepare the required materials according to the formula to ensure that each material met the requirements. Then, the surface active agent, the solution, and the auxiliary agent were prepared into a solution according to a certain ratio. Next, he added solid ingredients such as lemon acid and soda powder into the solution and stirred it evenly. The evenly mixed solution was poured into the mold and added with preserving agents to stabilize it. Finally, he poured the mixed dishwashing liquid into the mold and placed it in a dry place. He waited for it to cool and solidify. After demoulding, he could use it.
It should be noted that the formulas and methods provided above are only for reference. The specific formulas and production methods may vary according to different needs and manufacturers. For the production of dishwashing liquid in the factory, due to the need to meet the requirements of appearance and effect, the production formula would be more stringent. It may need to be analyzed and tested by a professional third-party testing agency to determine the specific composition and ratio of the formula.
" The formula and manufacturing method of the dishwashing liquid include the preparation and mixing of the components such as the surface active agent, the solution, and the auxiliary agent, as well as the addition of the solid raw materials and the cooling and demoulding steps. The factory's production of dishwashing liquid may require stricter formula requirements and professional analysis to determine the specific composition and ratio of the formula.
Silicate cement was a kind of hydraulic cementation material, and its main component was calcium Silicate. According to domestic standards, the cement was made of cement clinkers, limestone or pulverized blast furnace slag, and a suitable amount of fine plaster. There were two types of portland cement. One was portland cement without mixing materials, and the other was portland cement with mixing materials. The portland cement has the characteristics of fast setting and hardening, high early strength, and good frost resistance. Ordinary portland cement was a type of portland cement. It had a fast hydrating reaction speed and high early and late strength. The composite portland cement is a hydraulic binding material made of portland cement grog, two or more mixed materials, and an appropriate amount of plaster. White portland cement is a kind of hydraulic binding material made of portland cement with less iron dioxide content. In general, portland cement was a common cement type with many types and uses.
