Does citric acid (lemon juice?) evaporate quickly?
So, I had about 1 liter of water, and I left it out for 24 hours. The pH after 24 hours was around 8.0. Using lemon juice, I ph-ed it to 6.0. I used some of this to germ seeds. In another 24 hours, that same water had a pH again quite high (over 7.0). I used a typical popcorn-sized bowl to hold the water. Are the acidic components of the lemon juice evaporating, or is even more chlorine evaporating after the initial 24 hour period of sitting out? Thanks guys. PS. Is a store bought “ph-up/down” somehow better than baking soda / lemon juice ?

According to some of the posts here and organic chemistry, citric acid is not an ideal choice to buffer an alkaline solution since it is such a weak acid. This me
