Re: How to free a steel to Aluminum corrosion bond
If I read the label, and the %&$# marketing department had the decency to give me the percentage of acid, how much water should I add to a 15% or 32% solution to do this job?
In the safety first department, pour the acid into the water. If you add water to acid, a drop can boil and the steam explosion can splatter acid all over the place.
A 50/50 solution of 4 molar muriatic acid water is nice information, if you remember the high school chemistry class that I slept through in 1967. For those who have lead a normal life blissfully free of mols and where normality doesn't depend on the equivalence factor, we buy muriatic acid in a 15-38% solution, depending on the brand at the big box store. Hopefully we follow the directions before we use it to clean the driveway. 4 molar is a 14% solution. The stuff in the store is usually 32%, but sometimes it is 15%, and sometimes it is something else. You need to read the fine print on the label and we need some clarification.
So,what have we here? Is it a 4 molar (15%) solution from Lowes swimming pool department diluted with an equal amount of water? Is it the 32% stuff from the paint department diluted with an equal volume of water to make a 4 molar solution?
The 'green' garbage from Walmart says that the fumes are reduced so much that it must be a weak acid solution in a bottle of over priced water.
