1.	Identify the salts P and Q from the observations given below:(i) On performing the flame test salt P produces a lilac coloured flame and its solution gives a white precipitate with silver nitrate solution, which is soluble in Ammonium hydroxide solution. (ii) When dilute HCl is added to a salt Q, a brisk effervescence is produced and the gas turns lime water milky.When NH4OH solution is added to the above mixture (after adding dilute HC1), it produces a white precipitate which is soluble in excess NH4OH solution.
Answer» (i) KCl (ii) ZnCO₃
