Question

lemon juice has ph-2,what is the concentration of h+ ions​

Answer 1

Answer:

pH or pOH is the measure of acidity or alkalinity of a solution.

pH is calculated by taking negative logarithm of hydrogen ion concentration.

Acids have pH ranging from 1 to 6.9, bases have pH ranging from 7.1 to 14 and neutral solutions have pH equal to 7.

pH=-\log [H^+]pH=−log[H

]

pOH=-\log[OH^-]pOH=−log[OH

]

Putting in the values:

2=-\log[H^+]2=−log[H

[H^+]=antilog(2)=10^{-2}[H

]=antilog(2)=10

−2

Thus the concentration of H^+H

ions are 10^{-2}M10
