It's a polyatomic ion made from 2 sulfide ion. It's formula is 2S(2)
The valence of a bisulphite ion is -1; its formula is HSO3-1. (Although the name bisulphite is still acceptable, it is now considered preferable to call it "hydrogen sulfite ion".)
Potassium bisulphite is commonly used as a food preservative to inhibit microbial growth and oxidation. Studies on its effectiveness under various conditions, such as different concentrations, temperatures, and pH levels, can help determine the optimal conditions for preserving food products. This research can provide valuable insights into the mechanism of action of potassium bisulphite and its potential as a safe and effective food preservative.

Yes, a project on the effect of potassium bisulphite as food under a various condition is a good one for someone taking a course in Food Science.
Sodium hydrogen sulphite: Sodium bisulfite, not sodium "meta" bisulfite
Sodium Bisulphate is dry acid for swimming pool use.

HO-C-OSO2 + OH- yields C=O + SO2 and H3O+
Fe(II)(HSO3)2 Iron(II) bisulphite . NB sulphurous acid is H2SO3 . Its anion is Sulphite (SO3^2-) The ''bi' means the sulphurous acid has only 'lost' ONE(1) hydrogen Hence the sulphite becomes the 'bisulphite' (HSO3^-) Since the iron is in oxidation state '2' , its cation is Fe^2+. Hence it needs two 'bisulphite' anions to balance the charges. NNB Do not confuse the 'bi' to mean 'two'. In this case it refers to the loss of hydrogen from the acid, in a similar way to sodium bi-carbonate (NaHCO3). Hope that helps!!!!
Bisulphite is HSO3, otherwise known as hydrogen sulfite. This has a -1 charge, therefore there is 1 K+ needed to balance this. The chemical formula is thus, KHSO3.
Campden tablets (or Sodium meta-bisulphite tablets) are used in brewing and wine-making. Any large supermarket, or any shop that sells brewing equipment should stock them.
This does not exist. If it did, it would probably be something like "Copper(III) hydrogen sulfide"
Carbonated Water Glucose Fructose Syrup (24%) Orange juice from Concentrate (5%) Citric Acid Preservatives (Sodium Benzoate, Sodium Bisulphite) Stabilisar (Acacia Gum) Caffeine (0.012%) Antioxidant (Ascorbic Acid) Flavourings Colour (Beta-Carotene)
Postassium bisulphate - KHSO4 - can be used as an food preservative to protect the food from micro-organisms.
