Homework Answers
Answer : Yes
Q = 8.99 x 10-8
Ksp of PbSO4 = 1.6 x 10^-8
If Q>Ksp . precipitate will form
Pb(CH3COO)2 concentration in the mixture = 15.0 x 4.99 x 10-4 / (15 + 25) = 1.87 x 10-4 M
Na2SO4 concentration in the mixture = 25 x 7.69 x 10-4 / (15 + 25 ) = 4.81 x 10-4 M
solid formed is PbSO4
Q = [Pb2+][SO42-]
Q = (1.87 x 10-4)(4.81 x 10-4)
Q = 8.99 x 10-8
As reaction quotient Q>Ksp, precipitate will form
NOTE- you please upload next problem separately. Questions that are posted on the boards all differ in length and complexity. They often include subparts- like a, b, c, d, i, ii. In order to make the best use of your valuable answering time, please follow the following protocol for questions with many subparts:
- more than 1 question: answer
the first question
- Unless a student explicitly mentions a question to answer- for instance, “answer the third question”. In this case, the question requested should be the one answered.
