Is my acid of .675 anthing to worry about?
My book says I can cold stabalize, and it might lower it.

I will be putting it in my fridge shortly.
I can leave it in there until the weather outside is colder.

I recalabrated my PH meter. It seemed like it was off.


My new acid is .675 with a PH of 2.94
I also took a reading from a jug that I did not oak, it was .650 and
PH 3.00


By the time I got 8.62 the test vial seemed rather dark.
I assumed it was complete when it went from pink to gray.
it was a gray/blue color.
If that is the actual end point then my acid is .725


The standard endpoint for NaOH titrations is the phenolphthalein
endpoint, which is 8.2 .

I've never heard of anyone using 8.62 before. Is that a French
thing, like referring to the acid levels as g/l of sulfuric, even
though there's (one has to hope) no sulfuric there?
