Question

What is the pH of a 0.00162 M NaOH solution?

Answer 1

We know [from here](https://socratic.org/questions/what-is-the-ph-of-a-5-00-x-10-2-m-aqueous-solution-of-ba-oh-2`414169) that`pH+pOH=14#. And this has to be committed to memory.

Explanation:

So we calculate `pOH`, i.e. `pOH=-log_10(1.62xx10^-3)=2.79`. This is by definition of `p` function.

But `pH=14-2.79` from the above, so `pH=??`

Is this an acidic or basic solution? Why?
