- everyday chemistry - Sugar solutions have a neutral pH in themselves . . .
I'm not an expert, but as far as I understood a sugar solution is completely neutral since sugar can't take hydrogen ions out of the water or donate them in Sugar is a non ionic compound, so it do
- Why does my sea salt have a best by date? [duplicate]
@Farooq: As the link in this answer shows, culinary “sea salt” certainly can contain anti-caking agents And as the answer explains, the (potential very slight) deterioration that justifies the “best before” date is not caused by the anti-caking agent, but inhibitied by it Best before dates are never meant to be interpreted as “product expires now — discard it”, but just as
- Why is a C4 ring impossible? - Chemistry Stack Exchange
Ring strain and principles of aromaticity render such a molecule unstable Each double bond contributes 2 π electrons, and with four double bonds in one cycle in common, there is a total of 8 Compounds with (4n + 2) π electrons (where n is an integer number) are considered as Hueckel aromatic with an additional energetic stabilization e g , in benzene compared to a hypothetical cyclo-1,3,6
