What is universal indicator?
It is a substance used to determine the strengths of acids and alkali.It changes color according to the pH of the material its in. It is so useful because the color also tells you how strong the substance is. As an example, if you were to put a few drops of the indicator in water it would go green. A few drops of it in cleaning products and it would go a deep purple.A universal indicator can give various colors to a huge variety of pH ranges.
When antifreeze is added to water the freezing point of the water is what?
It drops to about 12 degrees Fahrenheit.
What is the specific name of universal indicator?
A Universal indicator is a pH indicator composed of a solution of several compounds that exhibits several smooth colour changes over a pH value range from 1-14 to indicate the acidity or basicity of solutions. A universal indicator is typically composed of water, propan-1-ol, phenolphthalein sodium salt, sodium hydroxide, methyl red, bromothymol blue monosodium salt, and thymol blue monosodium salt.
What is the salt formed when 1 ml of SbCl3 solution added a few drops of tap water?

If a few drops of universal indicator is added to water changes red what pH value is it?
Its Ph value is less than 7, so it is acidic. The exact colour change needs to be compared visually with a standard universal indicator chart to determine the precise Ph value associated with that particular shade of red.
How can you find out how acidic somethig is?
use the pH scale by adding 1 or 2 drops of universal indicator in an acid or an alkali
