Question
Give a chemical test to distinguish between the given pairs of chemicals:
Sodium chloride solution and Sodium nitrate solution
Advertisements
Solution
NaCl and NaNO3 solution can be distinguished simply by the addition of AgNO3 solution into it NaCl solution will give while precipitating of AgCl whereas NaNO3 will not.
`NaCl + AgNO_3 -> AgCl↓ + NaNO_3`
