Indicate is the base word for indicator.
acid-base indicators for all pHs: universal indicator for pH testing in general: indicator
base
This indicator changes his color.
An acid base indicator is a chemical substance that has the ability to change color depending on the pH.
A base will change the color of hibiscus indicator from red to green or blue, depending on the strength of the base.
Methyl indicator is typically found in its protonated form, which means it has the potential to act as a weak base when it accepts a proton.
A Base has a PH level of below 7
difference between acid base indicator and universal indicator
distinguish between common acid base indicator and universal indicator
Recreation of an indicator using an acid and a base involves mixing a colorless or faintly colored acid-base indicator with an acid to make the solution acidic (and change color) and then adding a base to neutralize the acid and return the indicator to its original color. This process demonstrates the reversible nature of acid-base indicators and how they can be used to visually indicate the presence of acids or bases in a solution.
abbas
The most appropriate indicator for a strong acid/strong base titration is phenolphthalein.
