3. Explain why an aqueous solution of sodium sulphate is neutral while an aqueous solution ofsodium carbonate is basic in nature. |
Answer» Because Sodium sulphate salt is made by reaction of sulphuric acid (strong acid) the sodium hydroxide (strong base) , thus on combining the opposite effects of acid and base neutralize each others effect completely leading to the formation of a neutral salt.Sodium carbonate salt is made of reaction of carbonic acid and sodium hydroxide . on combining the basic character will be more as a week acid can not neutralize a strong base completely . so the salt formed is basic in nature. |
