Oxalic Acid Recipes to Determine % Strength


#21

Thanks,

I am really trying to get past the “bathtub” chemist mentality that we all sometimes exhibit when we provide info in general terms.

When you say a bit of phos acid can you clarify that?

Say I am making a 1 gal batch of OA and using about 1 cup OA to get a 4% solution. How much phos acid would you add? What about surfactant?

I really hate just mixing things in what feels like a random manner without some sense of what it is I am doing, what I am trying to achieve and a valid starting point. I do my fair share of “bathtub” chemistry but usually it starts with some reference point and then calculated measurements of each item to reference with results and adjust accordingly.

On the issue of solubility of OA Powder into water. Everything I am researching indicates that warm to hot water in the standard when mixing the two. I even rigged up a 12 volt kettle to boil water from my softwash system on-site to mix OA when needed or make coffee in the morning (be sure not to mix your solution in the kettle - only boil water and pour into another container for mixing otherwise making coffee with OA might lead to some self poisoning).

I can’t give my formulas away, lol, my boss would kill me. I’ll throw you a bone and say less than 3% phos. Surfactant…well…depends on the surfactant. Many reputable surfactant choices listed on this site…some even with oxalic in the threads with surfactants :slight_smile:

The absolutely, by far, best and only thing about this whole thread, is picture of your wife. It’s funny, was looking to see how to use that mute button Steve was talking about the other day when you posted that. Now I’ll have to hang in there a little while.

Bahahahahahaha!!! I don’t wear a lab coat unless ordered to do so :-). In case y’all were wondering what I look like, here I am:

OK. Then let me be the first to comment. The first thing I see is a full set of teeth. I miss mine! Lost them almost a year ago. Although teeth have several mineral elements including calcium it is actually calcium phosphate. And the nanostructuring of that is beyond our puny abilities.

Not me chica! Takes me back to the '70s when physical science was cool, Trump was a failing real estate tycoon, and Ralph Northam was somewhere above the Mason-Dixon to throw up when you drank too much.
