Talk:Potassium sulfate

First talk section
The Link to the japanese page seems wrong, at least it links back to potassium carbonate... -- 217.186.243.101 23:30, 11 August 2005 (UTC)

and?
Why is this in club soda? It's not mentioned in either article. But this art6cle should mention why it's put into things we may drink. -Iopq 01:26, 13 November 2005 (UTC)

why does it say no-where why potassium sulphate does what it does please help me! — Preceding unsigned comment added by 82.3.225.246 (talk) 16:47, 18 December 2005 (UTC)

Arcanite
Is Arcanite really another word for this chemical? Dread Lord C y b e r S k u l l ✎☠ 12:05, 25 November 2005 (UTC)

Hardly an acidity regulator
Potassium sulphate may well have an E-number but it has no acid hydrogen and would be a very weak base. A SO42-/HSO4- buffer would probably have a very low buffer capacity, so I doubt that it would be used as an acidity regulator!150.227.15.253 (talk) 14:00, 12 October 2018 (UTC)
 * It's not unusual to use a weak base to limit acidity. -- Ed (Edgar181) 14:11, 12 October 2018 (UTC)

OK, i found information saying that a water solution would be pH 8-9.25 but that was for a technical grade so a more reliable value could be calculated from the pKa of HSO4-.150.227.15.253 (talk) 14:23, 12 October 2018 (UTC)
