Is universal indicator paper the same as blue litmus paper?
No totally different, universal indicator is a mixture of chemical which shows the precise p.H of a substance, blue litmus paper reveals whether the substance is acidic or alkaline.
When was universal indicator invented?
The universal Indicator was invented in 1923 by Yamada
Why might a scientist prefer to use Universal Indicator rather than a different indicator like litmus?
Litmus only differentiates between acidic and alkaline solutions. It does not give an accurate value of the degree of acidity of alkalinity. Universal Indicator can help measure the pH of the given solution as it does not just change from red to blue and vice versa, but in solution has a range of colours.
What is neutrilisation?
Neutrilisation is when you mix an acid and an alkali together. this, on a universal indicator, is 7 or green.

What is an indicator acid or alkali?
An indicator is a substance that changes color in the presence of an acid or alkali. Common indicators include litmus paper (blue for alkaline, red for acidic), phenolphthalein (colorless in acidic solutions, pink in alkaline solutions), and universal indicator solution (multiple colors to indicate pH level).

Does ethanoic acid turn universal indicator purple?
No, ethanoic acid (acetic acid) is a weak acid and will turn universal indicator a different color depending on its pH level. It will likely turn universal indicator red or orange indicating acidity.
