Metals higher in the reactivity series replace hydrogen from its acid to form the corresponding hydroxides and hydrogen gas.

Q. Rewrite the following by choosing the correct word from each pair in brackets.
Acids are compounds that contain (hydrogen/sulphur) atoms. Sulphuric acid is one such example. It is a (strong/weak) acid. It can be neutralised by (acids/alkalis) to form salts called (sulphites/sulphates).
Many (metals/non-metals) react with acids to give a gas called (hydrogen/oxygen). Acid also react with (carbonates/hydroxides) to give (hydrogen/carbon dioxide) gas.
Phenolphthalein turns (pink/colourless) in acids, while litmus turns (red/blue).

Nitric acid, even in its diluted form, is not used in the preparation of hydrogen from metals because metals on reaction with nitric acid can't replace the hydrogen atom.

Dilute acids like hydrochloric acid (HCl), sulphuric acid $H_{2} S O_{4}$ react with certain active metals to evolve hydrogen gas and form their metallic salts.
