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.

What control chart is most sensitive to variations in measurements?
I have seen this very question on a CQE practice test. The four possible answers were p chart, np chart, c chart and x and R chart. The first three charts are attribute charts and the last chart, x and R chart, is the only variables control chart. The only other possible answer could be x and s chart which tracks the standard deviation vs the range.

What does universal indicator test for?
A universal indicator changes color in response to the pH of a liquid. Do determine the pH of the liquid, you need to refer to a color chart that tells you which color indicates which pH.
What colour will universal indicator turn when mixed with a weak acid?
a bit of an weak orange colour, just look at any image of the chart
How are universal indicators useful to scientist?
An Universal Indictator is more helpful because it shows the exact amount of acidity. Other indictators (example the red and blue litmus) just indicates whether or not the solution is acidic. The universal indicator gives you a specific color to which you can match a pH number therefore, telling you how acidic the soultion is.
Do acids turn universal indicator solution green?
Universal Indicators vary slightly, so always consult the colour chart provided by the manufacturer, but acids tend to give reds, oranges and yellows.
What do you use universal indicator solution for?
It is a chemical solution used for knowing the pH of a substance. Eg. You mix a drop of Universal indicator solution with approx 5 mL of the substance whose pH you want to know.You can compare the color with a standard pH chart and know the pH.
If a few drops of universal indicator is added to water changes red what pH value is it?
Its Ph value is less than 7, so it is acidic. The exact colour change needs to be compared visually with a standard universal indicator chart to determine the precise Ph value associated with that particular shade of red.

Why can't you use a pH chart with litmus paper?
Litmus paper only shows if a substance is acid or alkali. It will turn red if its cid, or blue if its alkali. It doesn't show how acidic or alkaline it is (ie, the pH). This is what universal indicator shows.

PH method to determine a pH of a substance?
Dip an indicator into the substance and compare the colour to the chart.
What color does Universal indicator turn in diluted hydrochloric acid?
Hydrochloric Acid is known to be a very strong acid. A 0.01 molar solution of HCl has a pH of 2 ( -log(0.01) ) which on the pH scale is very acidic (under 7 is acidic, 7 is neutral, over 7 is basic). On a universal indicator test, HCl would come out as red. A basic solution would be a more blue-green, or green depending on the concentration.This is a color chart for a universal indicator test:http://chem.csusb.edu/images/pH_chart.gif
