Red cabbage juice.
It measures pH from 2-12.
A pH meter will identify acidity and alkalinity.
Acid turns it in red, while base will turn it blue.
Acids- turn blue litmus paper to red, sour, pH < 7 Bases- turn red litmus paper to blue, bitter, slippery, pH >7 Neutral is a pH of 7
Acids all- *Taste sour *Turn blue litmus paper red *React strongly with other elements, especially bases
The most common method is to use something called litmus paper, which comes in both red and blue. When you dip the red litmus paper in the substance, if it turns blue, then the substance is a base. When you dip the blue litmus paper in the substance, if it turns red, then the substance is an acid. However, this doesn't give you the exact pH of the substance, so there are several other devices that you can buy that measure pH.

The reaction between acids and bases is called neutralization.
I would dip litmus paper into each solution. If the litmus paper turns red the solution is an acid, if it turns blue the solution is a base.
there are other indicators that can be used - universal Acid-red Base-Blue Neutral-green methyl orange Acid - red Base - yellow
Acid rain, like other acids, turns blue litmus paper red (pink).
blue litmus paper turns to red when its in contact with acid
With a pH meter or pH paper. Other indicator dyes (e.g. litmus, phenolphthalein) may be used if it is not necessary to determine the exact numerical pH value.
Acids + Bases pretty much neutralise each other. They produce salt and water when mixed.
The simplest way is to use litmus papers. Acids turn blue litmus paper red; alkalis turn red litmus paper blue. Other ways include the use of indicators such as universal indicator or methyl orange.
