Calculate the pH if the [H]=0.000001

Answer: pH is 6

Explanation:

Given that,

pOH of solution = ?

[H+] of solution = 0.000001M

Recall that pH is the negative logarithm of hydrogen ion concentration in the solution. It is mathematically expressed as:

pH = - log (H+) where H + is the concentration of hydrogen ion.

So, pH = - log (H+)

pH = - log (0.000001)

pH = - (-6)

pH = 6 [The two minus signs cancelled out]

Note that pH value of 6 is mildly acidic because any pH value less than 7 is said to be acidic

Thus, if the [H]=0.000001 the pH is 6
