  • Sodium Bisulfate vs Sodium Bisulfite - Chemistry Stack Exchange
    The food additive code (the E number, which is commonly found on food labels) of sodium hydrogen sulfite is E 222 Sodium hydrogen sulfate or “sodium bisulfate” (NaHSO 4) is used as acidity regulator The food additive code of sodium hydrogen sulfate is E 514
  • Why is HSO4- shown as an example of a weak acid instead of HSO4?
    The bisulfate molecule doesn't exist in solution I can only find references to the hydrogen sulfate molecule as part of salts, which implies that hydrogen sulfate is usually found as an ion The bisulfate (hydrogen sulfate) ion is indeed an acid It is a relatively strong weak acid too, with a $\ce {K_a}$ value of $1 2 * 10^ {-2}$ Part of the reason for its acidity has to do with its
  • How do I get a 20% ratio of sodium bisulfate with 1 gallon water?
    4 This isn't something that requires 0 1% precision The link says "40 grams of sodium bisulfate in 160 ml of tap water " 160 ml of tap water is very close to 160 grams A gallon of water is reasonable close to 4 liters or 4000 grams $\dfrac {4000} {160} = 25$ $25 \times 40 \text { grams}= 1000 \text { grams} \approx 2 2 \text { lbs (gallon
  • terminology - Why are there no bichloride or binitrate ions, like . . .
    I have been thinking lately that if there is bicarbonate why is there no bichloride or binitrate Please someone give an easy explanation
  • Why is sodium bisulfate acidic? - Chemistry Stack Exchange
    Sodium bisulfate $\ce {NaHSO4}$ has still one acidic hydrogen, as sulphuric acid is a diprotic acid, therefore it is acidic By other words, just a half of sulfuric acid is neutralized here
  • everyday chemistry - I need to know whether Lead (II)Bisulfate is . . .
    I need to know whether Lead (II)Bisulfate is soluble because I couldn't find any information on it online [closed] Ask Question Asked 1 year, 5 months ago Modified 1 year, 5 months ago
  • Why was the prefix bi used in compounds, such as for bicarb of soda?
    Similar explanations make sense for bisulfate and bisulfite The acid-base reactions that a sulfate or sulfite ion might undergo are already partially completed in the bi- versions of the compound, so it takes twice as much sulfate or sulfite to do the same job as the non-hydrogen form The hydrogen phosphates don't fit this pattern as nicely
  • Bisulfate vs Hydrogen sulfate - Chemistry Stack Exchange
    What's the difference between bisulfate and "something" hydrogen sulfate? Has there historically been a preference for one over the other?
  • HCl synthesis from sulfuric acid and sodium salt
    First, it occurs stepwise, with the acid salt sodium bisulfate as an intermediate The first stage happens at room temp between equal proportions of salt and sulfuric acid
  • Whats the reaction between H2SO4 and NaH2PO4?
    Actually you have two reactions, since sulfuric acid can give off two protons: $\ce {H2SO4 + NaH2PO4 -> NaHSO4 + H3PO4}$ $\ce {NaHSO4 + NaH2PO4 -> Na2SO4 + H3PO4}$ The $\ce {NaHSO4}$ is called sodium bisulfate Bisulfate is the thing you form first when sulfuric acid acts as an acid, then you get the sulfate ion if you have a strong enough base to react with the almost but not quite strongly
