Description : If I add two tbs citric acid to 32 oz white vinegar (5% acidity) how much willthat increase the total acidity of the solution?
Last Answer : I hope you get a knowledgeable answer. I too would like to know. However, wouldn't the acidic content wash away fairly soon? At the very least I think the first rain would dilute it. I have an area I ... and I've dug up some but that too is too much. Perhaps after the weekend we will get an answer.
