What is the colour of bicarbonate of soda added to universal indicator?
pH 5.6
What is a pH indicators?
A pH indicator is a halochromic chemical compound that is added in small amounts to a solution so that the pH (acidity or alkalinity) of the solution can be determined easily. Normally, the indicator causes the colour of the solution to change depending on the pH.

Why is important to choose an indicator that changes colour at a right pH?

What pH colour is a neutral?
The color is green for the universal indicator.
What colour uvirsal indicator go if added to soudium chloride?
Sodium Chloride a.k.a. table salt or sea salt is neutral and so Universal Indicator will go Green with a Ph 7
PH method to determine a pH of a substance?
Dip an indicator into the substance and compare the colour to the chart.
When water and universal indicator are added to magnesium oxide what colour does the solution go?
Copper oxide will turn blue or purple when Universal Indicator is put on it.If you found this helpful, please rate me :)
How do you know why the universal indicator will be a certain colour?
Depending on the pH solutions have different colors with a pH paper.
What is the difference between an indicator and a universal indicator?
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.
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.
What is the colour and pH of the aqueous solution of universal indicator at the beginning of the experiment?
Green
