The pH talk

Hello everyone! 🙂

I have received many questions about pH and therefore I have decided to make a brief post about it. In fact, to learn how to formulate and be able to make safe cosmetics at home, it is really essential that you understand what pH is and that you have a way to measure it.

Well then! Let’s dive in:
“pH” stands for “power of hydrogen”, the capital “H” is because the symbol of the element hydrogen in the periodic table is “H” (always capital! Now it should be easier to remember how it is properly written 🙂 ).

“pH is a logarithmic measure of hydrogen ion concentration in an acqueous solution” (don’t you dare stop reading!!! 😀 )

pH = -log[H+]

Try to think of it this way: by measuring the concentration of something (the hydrogen ion: H+) in an acqueous solution (water, for instance) we get to know how acidic or alkaline the solution is. 🙂
