Question

O sodium bromide precipitate forms. water forms. O no precipitate forms. QUESTION 5 When aqueous solutions of sodium chloride and silver acetate are mixed a. sodium acetate precipitate forms. O b. silver acetate precipitate forms O c silver chloride precipitate forms O d. no precipitate forms. QUESTION 6 Copy of For the balanced reaction below, d Initially 30 mL of 2.0 M sulfuric acic H2SO4+ 2 NaOHNa2S 0 a. sulfuric acid

Answer 1

In aqueous medium both sodium chloride and silver acetate is dissociated as follows-

NaCl $\rightarrow$ Na⁺ + Cl^-

CH₃COOAg ^{$\rightarrow$} Ag⁺ +CH3COO^-

Now there will be double displacement reaction between-

i) Ag+ and Cl^- to give AgCl precipitate (white colour)

ii) CH3COO^- and Na⁺ to give CH3COONa (sodiumr acetate)

AgCl is so insoluble in water that only 1.3 $\times$ 10^-5 moles of AgCl is present per litre of a saturated solution . Hence it will form precipitate. So, option C is correct.

sodium acetate is readily soluble in water and hence it will not form precipitate at all. so option A is not correct.

Silver acetate is also soluble in water and hence will not form precipitate, so option b is not correct
