Ph calculations

Question 1

What is the effect of temperature on Ph

Answer 1

Ionisation of water is an endothermic process
Higher temperature the formation of hydrogen and hydrogen ions is favoured as H+ is higher pH falls
At lower temperature the formation of water is favoured becuse H+ is lower pH rises

Question 2

Ph of water at different temps

Answer 2

at 100 degrees the pH of water is 6.14
at 0 degrees the pH of water is 7.47
both are neutral

Question 3

How to calculate pH of solution

Answer 3

pH = -log[H+]

Question 4

how to calculate H+

Answer 4

[H+] = 10^-pH
