Litmus Paper Red And Neutralizing Alkalis

An acid is a substance with particular chemical properties including turning litmus paper red, neutralizing alkalis, and dissolving some metals. It can be corrosive or it can be sour liquid of this kind. Acids are also all around us in everyday life, for example, carbon dioxide gas dissolves in rain to form carbonic acid (a weak acid). We find acids in many foods, such as ethanoic acid in vinegar. These acids are not hazardous. Some acids, which are found in the laboratory a car battery are too dangerous to taste or touch. Another name of these acids are strong acids. Alkalis are substances that are chemically the opposite of acids also including turning litmus blue and neutralizing acids. Some alkalis are found in everyday items such as soaps and cleaning products.
A pH of 7 is neutral and the color is green. When a pH less than 7 it is acidic. When pH greater than 7 it is an Alkali. The picture below shows the pH scale and what is weak and what is strong. The easiest way to measure the pH number of the acid is to use a universal indicator. There are three different types of indicators, like the main type universal indicator. Then the red cabbage indicator and the litmus paper. Litmus paper indicator solution turns red in acidic solutions, blue in alkaline solutions, and it turns purple in neutral solutions. Unlike litmus, universal indicators can show us exactly how strong the acid and alkaline solutions are. To use the red cabbage indicator, grind the red cabbage indicator until it turns out to be a purple colored juice. The purple colored juice turns red when it is mixed with something acidic and turns green when it mixes with Alkali. The red cabbage contains a pigment called anthocyanin that changes color when it is mixed with an acid or an alkaline. A pH less than 7, the pigment turns red in acidic environments. A pH greater than 7, the pigment turns bluish-green in alkaline environments.To prevent the strong acid spillage, there are some steps
