铝离子(Al³⁺)与氢氧化钾(KOH)反应分以下情况: 1. 当氢氧化钾少量时: - 化学方程式为:\(AlCl_{3}+3KOH = Al(OH)_{3}\downarrow+3KCl\)(以氯化铝为例,铝离子在溶液中,这里假设为氯化铝溶液),离子方程式为\(Al^{3 + }+3OH^{-}=Al(OH)_{3}\downarrow\)。 2. 当氢氧化钾过量时: - 首先发生\(AlCl_{3}+3KOH = Al(OH)_{3}\downarrow+3KCl\),然后生成的氢氧化铝继续与氢氧化钾反应,化学方程式为\(Al(OH)_{3}+KOH = KAlO_{2}+2H_{2}O\),总反应方程式为\(AlCl_{3}+4KOH = KAlO_{2}+3KCl + 2H_{2}O\),离子方程式为\(Al^{3 + }+4OH^{-}=AlO_{2}^{-}+2H_{2}O\)。 点击前往免费阅读更多精彩小说
When there was a small amount of oh-ions, the chemical equation of the reaction between aluminum ions and oh ions was: Al3 ++3OH - =Al(OH)3; when there was an excess of oh-ions, the chemical equation of the reaction between aluminum ions and oh ions was: Al3 ++4OH - = AlO2-+2H2O. When a small amount of oh-ions gradually becomes excessive, the chemical equation of the reaction between aluminum ions and oh ions is: AI (OH)3+OH - = AlO2-+2H2O. The ion equation for the reaction of aluminum with water is: 20H- +2Al+2H2O→ 2AlO2-+3H2. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The reaction of sulfuric acid (HNO2) and soda ash (NaOx) will produce NaNO2 and water (H ^O). The chemical equation is: HNO2 + NaOx = NaNO2 +H ^O. This was a typical alkali-base neutralizing reaction. The hydrogen ions (H) from the ionisation of sulfuric acid combined with the hydrogen ions (H) from the ionisation of sulfuric acid to form water. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
1. In an aluminum-Ni battery (negative pole-Al. positive pole- Ni. Electrolyte-NaCl-solution, O2), the chemical equation of the negative pole reaction is: 4Al12e- = 4Al3 +. 2. In a magnesium-aluminum battery (negative electrode-aluminum, positive electrode-aluminum, and an eletrolyte-lithium ion battery), the reaction of the negative electrode-aluminum battery was: Al3e +40H (-) = Al40H (-). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

There was no chemical reaction between the two of them. When the two of them dissolved in water, they would form a water solution, which would release a lot of heat. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The reaction equation of aluminum and water is: 2AI +6H2O ==(heating) 2AI (Ox)3+ 3H2 (boiling water); the reaction equation of aluminum and soda is: 2AI +2NaOx +2H2O = 2NaAlO2 + 3H2. There is also an equation for the reaction of aluminum and soda: 2AI +2NaOx +6H2O → 2Na [AI (Ox)4] +3H2. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Under the high temperature smelting conditions, the matte-making reaction can be expressed as: (FeS)+(Cu2O)=(FeO)+(Cu2S), the reaction's Gibbs free energy change is? G0 = -144750+13.05T (J), and the equilibrium constant lgK of the reaction at 1250 ° C is 9.86, indicating that the reaction is rapidly moving to the right at the smelting temperature. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The chemical equation of the reaction between hydrogen and Cl2 was H ^+ Cl2 = 2HQ (Condition: Illumination or ignition). [Phenomenon: When hydrogen and Cl2 react, if it burns quietly, it will emit a pale flame, and there will be white fog at the mouth of the gas collector. If hydrogen and Cl2 are mixed and illuminated, it will explode.] <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The chemical equation of the reaction between Na2SO4 and ClCl2 is Na2SO4 + Cl2 = NaHSO4 + Cl2. Because the HSO4 ^-in water was partially ionised, after adding a strong acid such as sulfuric acid, the reaction formed a weaker acidic HSO4 ^-ion. The ion equation for this reaction is: <i>(SO4 ^{2 - }+H^+ = HSO4 ^-<i>). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
