Back about 1956 I took a chemistry course called ‘‘quantitative analysis’’. Fascinating. I was musing recently about bicarbonate and vinegar [Armature gardeners like to speak of them as a cure for soil pH problems.] and I keep thinking, we had a formula which we could use to draw graph for bicarbonate and vinegar. Am I having daydreams about my youth? Can you link me to such a graph or formula?
This is what you’re thinking of. There’s coefficients for bicarbonate and vinegar, and with that, you can compute the equilibrium pH. The graphs are just a way to display the data - the way you solve it today is you use the formula and your calculator.
You figure out the equilibrium concentration of OH- or H+, and then there’s a simple formula that converts it to pH. You of course have to know the relative amounts of the bicarbonate and vinegar.
I hope you mean amateur gardeners, OP.
Either that or she’s talking about animatronic topiary…
Based on what you’ve said,I’m guessing you are asking for titration curves. pH curves (titration curves)
We do have a fine crop of commutaters coming up this year.
Auto-correct is the worst enema of all posters…
I see what your spell-checker did there.
(Nothing like a malspellcheck to derail a thread in 1.)
That’s it Thanks.
It is amazing how much one can forget. I aced that course and now I didn’t even remember what to ask. Thanks again.
