A pH meter uses a probe and voltmeter to measure pH digitally. Universal indicator is a mix of indicators that change colour to indicate the pH of the solution. pH meters are accurate and will detect changes quickly, whereas universal indicator is slow to change colour to indicate pH change.
An indicator is a substance that changes color in response to changes in pH, indicating the acidity or alkalinity of a solution. A universal indicator is a mixture of indicators that can show a range of pH levels by changing color, making it more versatile than a single indicator.

What effect does an acid have on universal indicator?
An acid will cause universal indicator to change to a red color, indicating a pH level between 0-3. This color change occurs because the acidic conditions cause the indicator molecules to shift their absorption spectrum towards the red end of the spectrum.
What is the colour of the universal indicator in the acid?
The universal indicator turns red in acidic solutions.
What colour universal indicator turns to a neutral?
Green is the color that universal indicator turns to when it is neutral.
What coulor do alkalis turn universal indicator?
Alkalis turn universal indicator blue or purple.
What is the colour of ammonia on a universal indicator?
Ammonia typically appears blue on a universal indicator.

Why does universal indicator not always give an accurate result?
Universal indicator is just that - an indicator. It is not intended as an accurate measurement system.
