1. I assume the answer is H2SO4; however, you should be aware that only the FIRST H is a strong acid, the second H is weak (a strong weak but it is not 100% ionized).

2. I'm confused with this question posted by Lauren.

I thought that :
H3PO4
H2SO4
HNO2

were strong acids... but I was just taught to memorize a table of strong acids and bases and that the rest were all weak.
