Hi, can you confirm that only magnesium with water will give me a much lower PPM concentration than the combination of malic acid and magnesium? I feel like my poles don't work anymore after just two uses

The magnesium rods after some uses will also have gotten an oxide layer on it, which the weak acid will take off and expose raw magnesium.Hi, can you confirm that only magnesium with water will give me a much lower PPM concentration than the combination of malic acid and magnesium?

@Hip Hi everyone, I tried the test tube method. I cut a 10 g bar into 3 parts and put 1/3 inside the test tube with the quantity of vinegar that exceeds the bar, closed the cap and made the hole. When I insert the test tube into the bottle of water, why doesn't it sink to the bottom but remains afloat with the cap on the surface? Where am I doing wrong ? Thank youI don't know for sure, but the reaction of Mg with water is much slower, so unless you leave it for days, you will not get much H2 produced. Whereas the reaction with malic acid is fast and intense.

@Hip Thanks, while regarding the ratios, how can I determine how many grams of acetic acid there is if I simply fill half a test tube with vinegar? the bar weighs 3g.
