Determine the pH of the following solutions.

Question

1) 0.600 M HCl
2) 0.052 moles of H2SO4 dissolved in 4.2 L of water.
3)5.6 grams HNO3 dissolved in 450 ml of water.
4) 2.5 grams of NaOH dissolved in 500 mL of water.
5) adding 2 grams NaH dissolved in 0.56 L of water.
6) 20 mL of 0.27 M HNO3 is diluted to 500 mL.

Answer 1

All of these are the pH values for strong or weak acids. What is it you don't understand. Be specic.

Answer 2

You have to determine the pH of these solutions. These are acid-base questions.

Answer 3

I know that. What is your problem in understanding these. Be specific. I need to know what you don't understand so I'll know where to start explaining.

Answer 4

I think I understand 1) and 2) but I do not understand how to calculate the pH when it is dissolved and diluted.
