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.

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?
pH of ammonia is around 11-12. Hence when you put it in a universal indicator, you get purple color.

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.
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.
