Topic 2 Topic 2 Common acids sulfuric acid sulfuric acid Review: chemical properties of hydrochloric acid (containing H+) 1, with the indicator function, the acid solution can make the purple litmus red acid solution can make the purple litmus red colorless phenolphthalein TS discoloration discoloration colorless phenolphthalein TS 2, the metal reacts with hydrochloric acid (a replacement reaction). The metal reacts with hydrochloric acid (a replacement reaction) Metal + hydrochloric acid salt + hydrogen 3, reaction of metal oxide and hydrochloric acid (double decomposition), reaction of metal oxide and hydrochloric acid (double decomposition) Metal oxide + hydrochloric acid + salt + water 4. Reaction of base with hydrochloric acid, Alkali + hydrochloric acid + salt + water It is a neutralization reaction (a double decomposition reaction) that is a neutralization reaction (belonging to a double decomposition reaction) 5, salt reacts with hydrochloric acid, Salt + hydrochloric acid + new salt + New acid Note: we usually encounter the salt is carbonate, because note: we often encounter is the formation of carbonate salt, acid carbonate, the generation of acid is carbonate, carbonate has the most unstable reaction is. Therefore, most reactions are: hydrochloric acid + carbonate + new salt + water + carbon dioxide Supplementary experiment Silver nitrate and dilute hydrochloric acid reaction AgNO3 + HCl = AgCl + HNO3 reaction: the essence: Ag+ + Cl- = AgCl: Thinking: thinking: 1, how to test compounds containing Cl-? How do you test compounds containing them? Adding proper amount of AgNO solution, adding proper amount of AgNO3 solution, if the insoluble white precipitate is produced, the white precipitate of dilute HNO3 is pr
