Worksheet: Tests for Halides

In this worksheet, we will practice describing the use of ammonia, sulfuric acid, and silver and lead nitrates to test for the presence of halide ions.


When 1.1324 g of a solid sample containing chloride ions is dissolved in an aqueous solution of excess silver(I) nitrate, 1.0881 g of silver(I) chloride precipitates. Calculate to 4 significant figures the mass of chloride ions in the sample as a percentage of the total sample mass.
