    Year 11 acids and bases help!

    This is not a homework question but I was just wondering if the way I answer questions to do with the neutralisation of acids and bases was right (specifically terminology) : Acids have H+ ions while bases have OH- ions. A neutralisation reaction occurs when the H+ ion and OH- ions cancel each...

    Properties of Weak Bases

    I'm so confused about this! My textbook seems to be contradicting itself. First it says that the conjugate bases of strong acids are weak bases, and vice versa, but then it says that some example of weak bases include the anions of WEAK acids. That doesn't make sense. Help!

    Acids and Bases

    in my notes, it reads that the: "dilution of vinegar results in lower acidity and higher percent ionization". is the acidity lower because concentration is decreased? and is % ionization higher because water ionizes more than a weak acid does? thanks!
