This question is impossible to answer because it depends on the concentration of the soap in the solution, the solution pH and the type of soap involved.
To illustrate, do you think that there would be a different pH if a small piece of soap was dissolved in a sinkful of water as opposed to a stronger solution made by dissolving a bar of soap in say 500ml of hot water?
Secondly, what type of soap are we talking about here? Cosmetic body soaps generally have a pH in the range of 5 to 8. Laundry soaps, which are made in a such a way to retain much of the lye etc that's used in their manufacture, typically have a pH of 10-12. Do you think that the type of soap used may have a bearing on the pH?
