The ph of a solution is measured as 4.5. what is the hydrogen ion concentration of the solution? a. 4.0 × 10-5 m b. 3.2 × 10-5 m c. 4.5 m d. 3.2 × 104 m

Answer : The hydrogen ion concentration is, (B)

Explanation :

pH : It is defined as the negative logarithm of hydrogen ion concentration.

Given:

pH = 4.5

Now put the value of pH in the above expression, we get value of hydrogen ion concentration.

Thus, the hydrogen ion concentration is,

explanation: it gains negative electrons, therefore becoming negatively charged. as charge cannot be created, nor destroyed, only transferred, this leaves the wool positive. now that they have opposite charges, the two items attract.
