I titrated (white zinfandel) wine with an autotitrator earlier today to find out it’s acidity and it changed colors all on it’s own; without using an indicator.
Yes but can I drink it?
Yeah; it has a nice robust finish of sodium hydroxide.
If it’s a neutral solution is probably fine. I don’t think NaOH is toxic when in a low pH solution.
I titrated it with a weak acid (or weak acids since there’s several in wine) and way past the equivalence point/s; so it’s mostly basic.
