what ion generally appears in the formula of a base? : Hydroxide

good job dude...all right!!

Yep, correct. Its not always as easy as looking for an h or oh to tell if its acid or base, but it works here. The way to remember: an acid is an acid because it can easily donate protons (h+ molecules) to another species, in general. So it makes sense that HClO4 is an acid, because it separates to H+ and ClO4 -, showing that it has a ptoton to donatr

looks good 2 me,

but then again .... I'm the character who was thrown out of CHEMISTRY
for being a FREE RADICAL!

yep these are all correct
