How does the solubility of basic salts change in acidic solutions?

• It becomes zero

• It increases

• It remains unchanged

• It decreases

Which type of salt has a solubility that is unaffected by pH changes?

• Basic salts

• All salts

• Acidic salts

• Neutral salts

What is the common-ion effect in the context of solubility?

• Adding a common ion increases solubility

• Adding a common ion decreases solubility

• Adding a common ion has no effect on solubility

• Adding a common ion turns the solution acidic

What happens to fluoride ions when an acid is added to a basic salt solution?

• They turn into frogs

• They turn into HF

• They remain unchanged

• They precipitate out

Why does adding acid increase the solubility of basic salts?

• It increases the temperature
