When naming oxyacids, change "-ite" to:

• -ate

• -ic

• -ous

• -ite

Answer explanation

When naming oxyacids, the correct way to change the '-ite' suffix is to replace it with '-ous'. This rule is followed in chemistry to indicate the presence of a lower oxidation state in the oxyacid. The other options, '-ate' and '-ic', are not correct replacements for '-ite' in this context.

When naming oxyacids, change "-ate" to:

• -ate

• -ic

• -ous

• -ite

Answer explanation

When naming oxyacids, the correct way to change the '-ate' suffix is to replace it with '-ic'. This rule is followed in chemistry to indicate the presence of an oxyacid. The other options, '-ate', '-ous', and '-ite', are not the correct replacements for this purpose.
