Question
Agl has K_sp = 8.5 times 10^-17, calculate the solubility of Agl in g/L. a. 4.1 times 10^-10 b. 9.2 times 10^-8 c. 2.2 times 10^-4 d. 2.2 times 10^-6 e. Cannot be calculated, not enough information provided. Which one of the following is the best indicator for the titration of acetic acid(HC_2 H_3 O_2)and potassium hydroxide(KOH)? a. indicator A, K_a = 6.5 times 10^-4 b. indicator B, K_a = 9.1 times 10^-6 c. indicator C, K_a = 3.4 times 10^-10 d. indicator D, K_b = 2.7 times 10^-10 e. All the indicators are the same.Explanation / Answer
Correct answer is (d) 2.2 x 10-6
Solubility product (Ksp)of AgI=[Ag] x[ I]
=S X S
Ksp=S2
S=Ksp
S=8.5x10-17
S=0.92x10-8 moles per litre
Solubility(S) in grams/litre=
=0.92 x 10-8x234
=215.28 x 10-8
=2.15 x10-6
=2.2x10-6
