PH method to determine a pH of a substance?
Dip an indicator into the substance and compare the colour to the chart.
What is the colour of bicarbonate of soda added to universal indicator?
pH 5.6
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.
What changes color at the endpoint of titration?
change in pH, changes the colour (of the indicator)
How are universal indicator and the pH scale linked?
its linked because universal scale is specificly diifferent in colour and scientist use it as acid tester also alkali.the ph scale is for testing if a indicator is a indicator
What colour would soap with pH 5.5 turn Universal Indicator?
The color is blue for a weak base.
Why is important to choose an indicator that changes colour at a right pH?
you
What pH colour is a neutral?
The color is green for the universal indicator.

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 colour and pH of the aqueous solution of universal indicator at the beginning of the experiment?
Green

What is the colour of universal indicator in ethanoic acid?
orange and PH of 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.
