0.10 M HCl 용액 50.0 mL를 1.00 L로 묽힌 용액의 pH

 

 

Calculate the pH of solution prepared by:

c) Diluting 50.0 mL of 0.10 M HCl to a volume of 1.00 L

MV = M’V’

( 참고 https://ywpop.tistory.com/2859 )

 

(0.10 M) (50.0 mL) = (? M) (1000 mL)

 

? = (0.10) (50.0) / (1000) = 0.0050 M

 

 

 

[HCl] = [H^+] = 0.0050 M

 

 

 

pH = -log(0.0050) = 2.30
