The chemical equation of the reaction between the acid and the salt is [2Na +2HQ = 2NaCl2 + H2], and the ion equation is [2Na +2H + = 2Na+ + H2]. (Here, taking sulfuric acid as an example, the principle of writing the reaction equation for Na is similar to that of other acids. The hydrogen ions in the acid are replaced to form hydrogen.)

In the presence of diluted sulfuric acid, the reaction equation is: K2Cr2O7 + 4H2O2 + H2SO4 (diluted)= K2SO4 + 2CrO5 + 5H2O; when the solution containing bichromate ions is heated with hydrogen peroxide2, the reaction equation is: Cr2O72- +3H2O2 + 8H+= 2Cr3 + +3O2 + 7H2O. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The chemical equation of the reaction between Na and sulfuric acid is: 2Na +2HQ = 2NaCl2 + H ^, which forms NaCl2 and H2. The chemical nature of the salt was very active. In this reaction, it would react with the acid to form a salt substance such as salt and a gaseous substance such as hydrogen. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The chemical equation of the reaction between calcium hydrogen and sulfuric acid is [2HNO_{3}+ Ka (SH)_{2}= Ka (NO_{3})_{2}+2H_2}O]. Because both calcium hydrogen and sulfuric acid were strong ions, most of them existed in the form of ions in the solution. The ion equation of the reaction was H^{+}+ SH ^{-}=H_{2}O). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Since the acidic nature of HCN was weaker than that of carbolic acid and stronger than that of hydrogen carbonate-based acid, the reaction equation between Cesium carbonate-based acid and hydrogen cyanic acid was: Cesium carbonate-based acid + hydrogen cyanic acid = Cs-based acid + Cs-based acid. Phenomenon analysis: Caesium dioxide is a white solid. During the reaction, the solid will gradually dissolve. Because the reaction produces caesium cyanidation (CsCe) and caesium hydrogen carbona-tion (CsHCO2), no gas is produced during the entire reaction. The solution remains colorless (both caesium cyanidation and caesium hydrogen carbona-tion solutions are colorless). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
