They are made of flowers and leaves
The indicator is litmus paper. :)
Indicators are substances that change color in response to the presence of acids or alkalis. pH meters and pH papers are commonly used to detect the acidity or alkalinity of a solution based on the color change of the indicator.
A universal indicator covers a broader pH range compared to litmus paper, which only gives a rough indication of acidity. Universal indicators provide a more accurate and detailed measurement of pH levels.
check if the sample is acidic or alkaline using litmus paper or the universal indicators
Litmus is a natural dye indicator extracted from lichens.They react with acid (blue litmus turns red)& bases(red litmus turns blue) .Paper made with litmus dye indicators are called litmus paper and used in chemical laboratories.
They all possess is litmus
The indicators in litmus are extracted from lichens; the color of litmus depends on the pH of the solution.
They are called indicators.
The indicators that tell us if a substance is acidic or alkaline include litmus paper, pH paper, universal indicator solution, and phenolphthalein. These indicators change color based on the pH of the substance they are in contact with, helping to determine if it is acidic or alkaline.
If a substance is an acid, it would turn red on a pH indicator
i know only litmus paper:l
An indicator used to detect an acid or base is a substance that changes color in the presence of acids or bases. Examples of indicators include litmus paper, phenolphthalein, and universal indicator solution.
