2.
11 of 26
What type of acid is sulfuric acid?
A diprotic acid.
12 of 26
What is formed if 1 H+ ion is replaced in sulfuric acid?
An acid salt.
13 of 26
What is the formula when sulfuric acid, H2SO4, is reacted with 1 sodium, Na, ion?
NaHSO4.
14 of 26
What does an acid salt behave as, and why?
An acid because the H+ ion can be replaced to form a conventional salt.

22 of 26
How much nitrogen does NH4NO3 contain by mass? [Ar: N-14, H-1, O-16]
1. Calculate the molar mass of NH4NO3: 14+(1x4)+14+(16x3)=80g mol^-1. 2. Calculate the mass of mitrogen in 1 mole of NH4NO3: 14+14=28g. 3. Calculate the percentage, by mass, of N: 28/80x100=35%.
23 of 26
