How will adding lemon juice to a soap solution affect the pH of the soap solution?

Question

anonymous · Answer

Soaps are alkali substances so by adding lemon juice (an acid substance) you will decrease the pH (because acid is low and alkaline is high) depening on the amount of lemon juice you add and the concentration of it would depend on your outcome, you may just make it slightly less alkali, you may neutralise it, or you may even acidify it if you were to add enough.
