A solution of acetic acid, hc2h3o2, on a laboratory shelfwas of undetermined concentration. if the ph of the solution wasfound to be 2. 68, what was the concentration of the acetic acid?

Sagot :

A solution of acetic acid , on a laboratory shelf was of undetermined concentration. if the pH of the solution was found to be 2. 68 , then its the concentration of the acetic acid was  2×[tex]10^{-3}[/tex]

Calculation ,

A figure expressing the acidity or alkalinity of a solution on a logarithmic scale on which 7 is neutral, lower values are more acid and higher values more alkaline.

We have to find concentration of the acetic acid .

pH = 2. 68

pH = -㏒[ [tex]H^{+}[/tex] ]

2. 68  = -㏒[ [tex]H^{+}[/tex] ]

[ [tex]H^{+}[/tex] ]  = [tex]10^{-2.68}[/tex]

[ [tex]H^{+}[/tex] ]  = 2×[tex]10^{-3}[/tex]
