What is pH and When to use pH strips and how to use them
ph Definition: pH simply explained, is a logarithmic scale and inversely indicates the concentration of hydrogen ions to measure the relative amount of free hydrogen and hydroxyl ions. pH measurements utilize a scale from 0 to 14 to specify acidity or basicity of an aqueous solution.
On one side of the pH scale are the acids, and the other side of the scale is considered alkaline also called "base." Acidic solutions are when measured and they have lower pH values. Strong acids are typically considered to be at pH of 0 to about 4.0 and become weaker up to what are considered mild acids at around 6.0 pH. Neutral is 6.5 to 7.3. Base solutions, also called alkaline on the pH scale are from about 7.4 to strong alkaline above 9.0 up to 14. (These descriptions of pH are relative depending on several factors.)
Water that has more free hydrogen ions is acidic, whereas water that has more free hydroxyl ions is basic. Since pH can be affected by chemicals in the water, pH is an important indicator of water that is change chemically.
Knowing the pH of a substance can be very important for many reasons. Safety is always a consideration, so knowing the pH before you handle something can prevent you from hurting yourself or others. Knowing the pH of a solution before handling is always safer. For example, it is always handy to have pH testing papers and have a way to test pH if you are working around the home with cleansers or even rainwater collected for plants. At work in a restaurant it is great to have a way to test the the sanitizing chemicals in use. If you are in a lab setting doing analytical chemical testing, it is very helpful, and safer to know the pH of a liquid, even water.
How to use pH testing paper:
* Always wear protective gear and review the Safety Data sheet of the chemical or solution being tested first. Testing the pH of a liquid has never been easier using our pH testing strips. After choosing the kit that best suits your situation, you will typically just dip a strip of the pH testing paper in to the solution you want to know the pH of. After dipping the strip in to the solution, compare the color on the strip to the color chart indicating pH included with the pH testing strip or kit. The color indicated will tell you what the pH of the solution is.
