(And, to be honest, I am not sure that all acids are miscible with water but I'd say they are)
Glacial basically means that: without water.
Formic acid is what ants lay down as a trail and they consist a bit of that.
Acetic acid (in photography we use a diluted form but can purchase it as 'glacial') is similar to that in vinegar which is generally a 5% solution
Hydrochloric (often times, and in hardware stores called 'muriatic') acid is what we have in our stomachs (gastric acid)
Sulphuric (sometimes in US, 'sulfuric') is used in batteries for autos in a dilute form
Nitric acid is very strong and able to reduce metals
Then a really strong combo of nitric and hydrochloric (1:3) is called aqua regia (king water) and that can reduce gold and platinum but even though it
is a mixture of acids I don't think it is technically an acid.
