Question

I will fail to dissociate. E) none of the above It will do sol V Sally. It will dissociate 14) If you had an aqueous mixture that contained Ag. different soli Terent solids could precipitate if a chloride solution was added A1 (B92 C) 3 D) 4 K contained Ag+, K+, and Pb2+ cations, how many AYA Kitcl > KCI) Pb²+ 200 - PbCl26) E) no solids will precipitate 3) What type of a reaction occurs when a potassium nitrate solution is made acetate solution? A) precipitation B) acid-base neutralization C) oxidation-reduction D) gas evolution E) no reaction a potassium nitrate solution is mixed with a barium nitrate and barium are soluble in water so no reachion. 16) What would be the formula of the precipitate that forms when Pb(NO3)2(aq) and K2504 (aq) are mixed? Double displacement (switch places. A) K(NO3)2 Pb(NO3)24 +K2504 sposou+ 2K NO3 (B) PbSO4 Red since all nitrates are soluble. C) PbK2 Pbson'w the precip. D) H20 E) none of the above 1113101 17) Considering the following precipitation reaction: Pb(NO3)2(aq) + 2KI(aq) + Pbl2(s) + 2NO3(aq) Which ion would NOT be present in the complete ionic equation? Pblz A) Pb2+ C) NO, E) all the above ions are in the complete ionic equation B) K+ Dr 18) Considering the following precipitation reaction:

Answer 1

#14. From the aqueous mixture of Ag^+ , K^+ and Pb^2+ , only Ag^+ and Pb^+2 forms solid precipitates with chloride ions as AgCl and PbCl2 respectively

While KCl is aqueous soluble salt.

thus there can be maximum 2 different solids .

Yours answer is correct.

Option (B) 2 is the correct answer.

#17.

Complete ionic equation of given molecular equation is ;

Pb^+2(aq) + 2NO3^-(aq) + 2K^+(aq) + 2I^-(aq) >>>> PbI2(s) + 2K^+(aq) + 2NO3^-(aq)

Thus all the ions are present in complete ionic equation.

Option (E) is the correct answer.

Kindly rate the answer. Thank you.
