0.200 M HCl 10.00 mL + 0.250 M NaOH. 0 mL
In a titration, 10.00 mL of 0.200 M HCl(aq)
is titrated with standardized 0.250 M NaOH(aq).
What is the amount of unreacted HCl(aq) and the pH of the solution
after the following volumes of NaOH(aq) have been added?
a) 0 mL

(0.200 mol/L) (10.00/1000 L) = 0.00200 mol HCl
---> unreacted HCl
[H^+] = [HCl] = 0.200 M 이므로,
( 참고 https://ywpop.tistory.com/12475 )
pH = –log[H^+]
= –log(0.200) = 0.699
