L1.1 – Kit Unboxing & Component Introduction

In chemistry,
pH is a measurement of the concentration of hydrogen ions in a water-based solution. A lower pH means that there are hydrogen ions in the liquid, whereas a higher pH indicates fewer hydrogen ions in the liquid.
In simple term,
pH is a scale from 1 to 14 that measures the acidity or alkalinity of a liquid. In the middle of the scale is pure distilled water, with a neutral pH of 7. Anything with a pH below 7 is an acid, and anything with a pH above 7 is an alkali, or base.

In its purest form, water has a pH of 7, which is at the exact center of the pH scale. Particles in the water can change the pH of the water, and most water for use has a pH of somewhere between 6.5 and 8.5.
