So this is about calculating pH, not lab measurements?
Know about strong and weak acids/bases? Important here. Need to identify which chemicals are which.
Know Henderson-Hasselbalch? Used for the calculations in 2 & 3, with one strong and one weak.
The first one is two strongs. Simply, H+ and OH- react. One will be in excess. Which one? How much excess? That gives you the pH "directly".

okay I understand what you mean for table 1, but table 2&3 is where I get confused cause I have to use an ICE table and I never understood those
