Question

The ph of a substance equals −log[h+] where [h+] is the concentration of hydrogen ions. [h+] for tomato juice is 10−4. what is the ph of tomato juice?

Answer 1

 The   Ph  of  tomato   juice  is  calculated  as follows

Ph  =  -log (H+)

if  H+   ion  concentration   is  10^-4

Ph  is  therefore =  -log  (10^-4)  =4

the  tomato  juice  has  a  Ph  of  4
