Question

distinguish between cacl2 and zncl2

Answer 1

cacl2 is calcium chloride and zncl2 is zinc chloride

Answer 2

Hello there,

To distinguish between the two solutions of Zinc Chloride (ZnCl2) and Calcium Chloride (CaCl2), we can use the following methods:-

1. By adding Ammonium Hydroxide solution (NH4OH) to both the given salt solutions, we will observe a gelatinous white precipitate of Zinc Hydroxide (ZnOH) in case of Zinc Chloride , while, no such observations i.e no precipitate will form in case of Calcium Chloride solution.

2. If we take anhydrous salt samples, then by simply keeping the two salts for a while, we will observe that a saturated solution of CaCl2 has formed, since CaCl2 is a deliquescent substance,while no such observations will be made in case of ZnCl2, in the span if time compared to CaCl2, i.e CaCl2 will form a saturated solution faster than ZnCl2.

However, I recommend that step 1 is a better experiment to distinguish between the two salts

Thank you, Hope you like the answer, please mark it as the brainliest answer
