Reactions of Acids Flashcards

All 7 cards in this deck

What are the products when a dilute acid reacts with a metal?

A salt and hydrogen.

What are the products when a dilute acid reacts with a metal oxide or a metal hydroxide?

A salt and water only.

What are the products when a dilute acid reacts with a metal carbonate?

A salt, water and carbon dioxide.

Which salts are made by hydrochloric, sulfuric and nitric acid?

Chlorides, sulfates and nitrates, e.g. nitric acid + ammonia gives ammonium nitrate.

What are the steps to write a balanced symbol equation with state symbols for a reaction of an acid?
e.g. magnesium + dilute hydrochloric acid

1. Write the formulae: $\mathrm{Mg + HCl \rightarrow MgCl_2 + H_2}$
2. Balance: $\mathrm{Mg + 2HCl \rightarrow MgCl_2 + H_2}$
3. Add state symbols: $\mathrm{Mg(s) + 2HCl(aq) \rightarrow MgCl_2(aq) + H_2(g)}$

What is the ionic equation for the reaction of magnesium with a dilute acid?

$\mathrm{Mg + 2H^+ \rightarrow Mg^{2+} + H_2}$

True or false? When a dilute acid reacts with a metal carbonate, the only products are a salt and water.

False. Carbon dioxide is also produced: acid + metal carbonate → salt + water + carbon dioxide.
