Study Notes

Acid-Base Reactions

A neutralisation reaction between an acid and a base produces a salt and water.
The general reaction between a metal oxide and an acid is the formation of a salt and water.
Copper oxide reacts with dilute hydrochloric acid to produce copper chloride and water.

Neutralization Reaction

The product of an acid-base neutralization reaction is a salt and water.
The reaction between an acid and a base results in the nullification of the acid and base properties.

Chemical Formulas

Acid-Carbonate Reactions

The main product when a metal carbonate reacts with an acid is a salt, water, and carbon dioxide.

pH Indicators

The color of phenolphthalein solution changes from colorless to pink when NaOH is added to it.

Acid-Base Neutralization

The effect of a base is nullified when it reacts with an acid to form a salt and water.

Reaction Products

The main products of the reaction between NaOH(aq) and HCl(aq) are NaCl(aq) and H2O(l).
