Question

Complete the table below by deciding whether a precipitate forms when aqueous solutions A and B are mixed. If a precipitate will form, enter its empirical formula in the last column. solution A solution B Does a precipitate form when A and B are mixed? empirical formula of precipitate x o ? sodium chloride ammonium bromide O yes o no zinc chloride potassium hydroxide O yes O no zinc sulfate sodium sulfide O yes O no

Answer 1

M preupitation reaction occurs in aqueous solution when one product is inscluble D Nadew + NHA Brew) - NaBrow) + N Halov) No precipitate formed because salts of Alkali metals are scluble Salbs of Ammonium are celso soluble 2) Zncz cout ROM (08) → Zn(OH)(5) Kellav) zinchloride potassium hydroxide Hydroxide of alkali metals cations and ca²t So²ta Baht are soluble Othaus are hydroride are insoluble o All halide are sceluble except lead (I), silver (I) & mercury (I) halides are Insoluble 3) zn so 4 coa) + Nagsaw) - Insoft Naz Sot na ) - Zinc Sulphate sodium sulphide Ohly group 1 metals, calcium & barium & Nhat sulfides aresaluble All others are insoluble All Sulfates are soluble except for Cath Banium, lead (II) & Shenhum sulfates are insoluble
