Question

calculate the pH of a solution obtained by mixing 50mlof 0.2M NaoH​

Answer 1

Answer:

calculate the pH of a solution obtained by mixing 50ml 0.2M HCI with 49.9 ml of 0.2 m NaOH solution. ... volume after mixing = 99.9 ml = 100ml. Hence, applying

N1V1 =N2V2,0.1×0.2 = N2×100orN2=2

4. in the final solution,

[HCI] = 2×10-4M, i.e., [H30+] = 2×10-4M.
