pH Indicators
What is pH?
pH, or “potential hydrogen,” is a measure of hydrogen ion concentration; a measure of the acidity or alkalinity of a solution.
When a solution is alkaline, or has alkalinity, it means it has the ability to neutralize acids. Alkalinity is expressed as a pH number, on a scale of 0 to 14. A pH of 7 is neutral; neither acidic nor alkaline. A substance measuring a pH level between 7 and 14 is alkaline, and is called basic (or a base). The closer a substance is to pH 14, the more alkaline it is. Foods are substantially made of water, so they also have a pH that can be measured. Because the human body is mostly liquid, it also has a pH, which is usually measured through blood.
What are some uses for pH Indicators?
pH meters are used primarily for home-based testing of tap and pool water. In most cases, tap water in developed nations are safe to drink, but accurate pH readings are necessary to ensure safe living environments for aquatic pets.
pH Book available in Single or Wholesale 100 Pack
Also available are the special range pH indicators so depending on what you are testing you will have an idea of what range you'll results will fall into and therefore choose a special range pH to get more precise results.
The special range pH are available in the following ranges:
pH 0-6
pH 0-14
pH 0.3-2.3
pH 1.7-3.8
pH 2-9
pH 3.6-6.1
pH 4.5-10
pH 5.1-7.2
pH 6-7.7
pH 6-10
pH 7-14
pH 7.5-9.5
pH 7.9-9.8
