Does citric acid turn red using a universal indicator?
You tell me!
What is the purpose of using universal indicator in titration?
A universal indicator is an indicator that changes color along with changes in pH level. The purpose of using it is to find a point at which a mixture of acid and base becomes neutral.
What is a indicator of acid and alkali?
acid should be a bright pink colour when using the indicator and alkali should go a greeny colour :) hope this helped you
What colour does universal indicator turn if you add vinegar?
Because oven cleaner contains Sodium Hydroxide (Na OH), a 'strong' alkali/base, to dissolve the grease, it would change Universal Indicator a deep blue/purple colour.
What is the colour change in the titration of KOH with H2SO4 using methyl orange as the indicator?
orange

3 How is the Universal indicator color chart used to measure acidity?
We measure pH by using a pH scale which has different colours on it which indicates the liquid. Universal indicator is a pH indicator that transitions through numbers 1- 14 (on a pH chart) to indicate the acidity or alkali of solution. A pH meter is an electric instrument used to measure the pH of a liquid which might be an acid neutral or an alkali. and there is my answer Lewis Jones park community school lots of substances change colour at specific pH values, so you have to use a colour chart for that specific substance. Universal indicator is a mixture of lots of different indicators so it changes colour many times throughout the entire pH range, and you can compare it to the universal indicator colour chart to find how acidic or alkaline your substance is.

How you can conclude the pH value of a fabric?
we can conclude by using a ph paper or universal indicator.
How do scientists measure food pH?
Through using the universal indicator or the PH probe.
How do you test of acids an bases?
using an universal indicator, or you can use litmus paper or a pH meter.
What is the colour change in the titration of KOH with H2SO4 using methyl orange as the indicator?
orange
What does yellow indicate on the ph scale?
It depends on what indicator you are using. Yellow with the bromothymol blue indicator is acidic, yellow with the methyl orange indicator is basic, yellow with the phenol red indicator is acidic and yellow with the universal indicator is acidic.
What is the purpose for using phenolphthalein for an acid base titration?
It's the colour indicator you watch for during the titration.
What colour would a neutral soloution become if universal indicator was added to it?
I don't know what you mean by "universal indicator". That's a generic term for a mixture of indicators that displays distinct colors over a fairly broad pH range, but without knowing which specific one you're using it's difficult to say. However, a lot of them are minor variations on Yamada's 1923 patent, so I'd expect that it would probably be somewhere in the greenish part of the spectrum. Exactly where depends on the particular ratios of the various indicator compounds used.
