• bitter taste

• slippery/soapy feel

What is a salt?

A compound formed by the replacement of a hydrogen ion in an acid with (a) metal cation[s]

What are the products of a reaction between an acid and a metal?

A salt and hydrogen gas

What are the products of a reaction between an acid and a metal hydroxide?

A salt and water

What are the products of a reaction between an acid and a metal oxide?

A salt and water

What are the products of a reaction between an acid and a carbonate?

A salt, water, and carbon dioxide

What are the products of a reaction between an acid and a hydrogencarbonate?

A salt, water, and carbon dioxide

What are the products of a reaction between an acid and a metal sulphite?

A salt, water, and sulphur dioxide

What are the products of a reaction between a base and an ammonium salt?

A salt, water, and ammonia gas

What are the products of a reaction between a base and a nonmetal oxide?
