Explain why the solubility of KHTar in 0.100 M NaCl solution differs from that in pure water?

Question

Explain why the solubility of KHTar in the mixed KCL - NaCl solution differs from that in the 0.100 M NaCl.

Answer 1

As the concentration of KCl in a solution increases, the solubility of KHTar ______________ because ___________________

Answer 2

Were you performing an experiment involving ionic strength?

Answer 3

It was a solubility lab for KHTar

Answer 4

I assume the answser is yes; NaCl increases the ionic strength and substances are more soluble as ionic strength increases.

Answer 5

What would the answer be to the second part? Explain why the solubility of KHTar in the mixed KCl- NaCl solution differs from that in 0.100 M NaCl

Answer 6

What is the concn of the KCl and NaCl in the mixture?

Answer 7

Concentration of KCl is 0.04 M and NaCl is 0.06 M

Answer 8

You are adding a common ion and that shifts the equilibrium to the left making it less soluble. See the link below.
