Question

The hydrogen ion concentration of a sample of each substance is given. Calculate the ph of the substance. (round your answers to one decimal place.) (a) oranges: [h+] = 2.5 × 10−4 m

Answer 1

As pH= - [H+]

If hydrogen ion concentration of orange juice is 2.5 x 10 raise to power -4. Then simply take a negative log of 2.5 x 10 raise to power -4, we get its answer.

pH = - log [ 2.5 x 10 ^ -4 ]

By rounding off to one decimal place. We get,

pH = 3.60
