Science Buddies: "Ask an Expert"

I want to do the Bath bomb experiment (https://www.sciencebuddies.org/science- ... p105.shtml), but I want to use citric acid substitutes instead of citric acid. I want to use lemon juice, lime juice, cream of tartar, and distilled white vinegar, but the citric acid is stronger than these substitutions. So how much of each should I use to make the bath bombs? Also, since some are liquids, it will change the recipe and I don't know how to even out the recipe.

I know that the citric acid is stronger than the citric acid substitutes, so I will probably need to use more of the CA substitutes than the recipe calls for. Since some of those substitutes are liquids, it will make the recipe uneven, and there will probably be too much liquid for the recipe. So, how do I even out the recipe when I have a larger amount of liquid that I need to use? How much of each substitute should I use and should I change the amount of dry ingredients in the recipe to even out the amount of liquid?

Didn't you ask that question on Monday?

Given the experiment and the response that A. Norman gave you, do you have idea of how to just try it and see what happens? The substitution sounds like a fun experiment.
