Litmus paper is an indicator used to test whether a substance is acidic or basic. At the bottom of the scale sits red, which represents the most acidic, and a dark blue at its opposite end represents 14 and alkalinity. Pure water is said to be having pH 7. The strength of the acidity or the basicity also cannot be determined using litmus papers, on the other hand, the readings are instantaneous, and easy to take. The indigestion tablets are bases.

Precision pH Paper:pH papers give more precise results. Red litmus paper is used to test if solutions are basic and turns blue when it encounters one of these. The directions for the liquid pH test generally require you to add a drop or two of the liquid into the water in the test tube. Here are some fun sites to visit if you want to learn more about chemistry and acids and bases. More specifically, the learners will be able to: — display appropriate behaviors when doing the labs. With standard litmus paper, look for one of two color options. What if we no longer had hospitals? Value pH Paper: pH papers can give the exact pH value of a solution.

However, it would be nice to have some examples or other reasons why and how one can use these strips in the household for everyday causes. Your indicator strips should come with a color chart to match shades to pH values. The paper used to make the litmus paper is free of contaminants that can cause color changes due to the pH of the solution. Normally this comes as a paper stripe. The primary raw material that is used in production of litmus is Lichen.

Oxidation is based on electrons. Red litmus paper can indicate alkalinity with a color change to blue. Blue paper that does not change color indicates the sample is a base. The pH of our bodies signalises our health and how healthy our body is. There are not very many substances that are commonly found to be neutral. The pH scale takes its name from the words potential of hydrogen. Real-Life Applications: There are many real life applications to this concept.

We have three different types of litmus paper: blue, red and neutral. The mixture should be soggier than mud, but without so much water that all the soil settles to the bottom quickly -- usually about twice as much water as soil works well. According to the reference given, a green color indicates a basic solution. Consult a medical doctor when needed. Other Options for Testing When you don't need exact pH numbers, try a test using basic household supplies.

The strength of the acids and bases on each bar differs. Nearly everything around is an acid or a base, with the exception of water. The pH number is used to rate the level of acidity or alkalinity of water-soluble substances. It turns red litmus paper blue. There is one more way to check the acidity of a substance and this its through litmus paper.
