Question

What are the pH of acids and bases?

Answer 1

A scale that measures the concentration of hydrogen ions in an aqueous solution.

Explanation:

pH is a logarthmic scale that is used to measure the concentration of hydrogen ions in an aqueous solution. It is used towards identifying how `"acidic"` or `"basic"` a solution is.

Acids are solutions with a low pH -> having a pH of less than `7`.
Bass are solutions with a high pH -> having a pH of higher than `7`.
There are also neutral solutions with a pH of `7`.

I'm not explaining acids and bases so I won't talk about them that much.

pH can be calculated by using the formula: `pH=-log[H^+]`. Where:
=> `pH` is the pH. Simple as that. No units - pH is not a unit.
=> `log` is the logarithm... because pH is a logarthmic scale.
=> `H^+` the concentration of hydrogen ions.

There are also things called pH indicators, that when reacting with a solution, will change a certain colour. Helpful to determine how acidic/basic an acid/base is.

I think that's the gist of it.

Hope this helps :)
