Which of the following is a characteristic of acids when dissolved in water?

• They produce hydroxide ions.

• They produce hydrogen ions.

• They have a pH greater than 7.

• They taste bitter.

The density of water is 1g/cm³ at a temperature of 40 C. This means that:

• The mass of 1 cm³ of water is 1 Kg

• The mass of 1cm ³ of water is 1 g.

• The mass of 1 m³ of water is 1 g.

• The mass of 1 cm³ of water is 1 L.
