If you want to get technical about things we can write out what’s happening as a chemical equation: acetic acid + sodium bicarbonate → salt + gas + water CH 3 COOH + NaHCO 3 → NaCH 3 COO + CO 2 (g) + H 2 O.$$\ce{2Al (s) + 3CuCl2 (aq) -> 3Cu (s) + 2AlCl3 (aq)}$$. No, I mean really old. Are there any safety guidelines for mixing sulfate with chloride? If copper(II) acetate is the product as suggested in answer two, then following the recommended approach for disposal is safe: You can bypass the problem by collecting the etch solution, and submerge aluminum foil. If I use a vinegar, Epsom Salts, and sugar, what is the balanced formula for the chemical reaction? Is the "chloride complex" (not sure if that's the right term) responsible for the green color that appears when salt is added (instead of the blue it would otherwise be)? Copyright © 2021 Multiply Media, LLC. Usually the acetic acid is produced by the fermentation of ethanol or sugars by acetic acid bacteria.

You can also replace vinegar with vinegar and baking soda solution, coke, corn syrup, salt water, tap water, etc.$$\ce{CH3C(O)OH + H2\color{red}{O2} -> CH3C(O)\color{red}{OO}H + H2O}. The end products are carbon dioxide (a gas) and water, in which two chemical products ( sodium ions and acetate ions) are dissolved. Why would the pressure in the cold water lines increase whenever the hot water heater runs. It is approximately 5-20% acetic acid in water. The oxygen then mixes with the iron, which is what causes the resulting exothermic reaction.
