Question

1. Sodium chloride and water
2. Sodium benzoate and water
3. Sodium benzoate and 1M HCl
4. Benzoic acid and 1M NaOH

Answer 1

As written this question can't be answered. How much solute in how much solvent?
1. Yes, NaCl is soluble in water in general.
2. Yes, sodium benzoate is generally soluble in water. It's a salt.
3. Sodium benzoate and 1M HCl not very soluble because the product is benzoic acid which is not very soluble.
