Calculate the value of H+), if the value of pH is 3.

Answer: 1.0 x 10^-3M

Explanation:

The solution with pH 3 is said to be acidic because pH values less than 7 are regarded as acidic, and will produce hydrogen ions.

Mathematically, pH is expressed as

pH = - log (H+)

where H + is the concentration of hydrogen ion

So, pH calculations are as follows

3 = - log (H+)

(H+) = Antilog (-3)

(H+) = 0.001M

Place (H+) in standard form

(H+) = 1.0 x 10^-3M

Thus, the value of hydrogen ion (H+) in the solution with pH 3 is 1.0 x 10^-3M
