What happens when you add universal indicator to water?
A change of color specific for acids, red-brown for Merck pH indicators.
What color does universal indicator turn in deionized water?
since water is pretty neutral, the water does not change color but the universal indicator does. The universal indicator changes color as per the quantity of deionized water... But it changes to straw color or pale yellow in 50mL of deionized water.
Why does the typical base indicator exhibit its color change over a range of about 2 PH units?
The usual range of the color change on the indicator is between 1.5-2 pH units because of the sensitivity of the indicators. The universal indicator is used in most test.
When a drop of universal indicator is added to water what is the colour change?
Pure water is neutral so the color will be green.
What chemical indicators are and what they are used for?
chemical indicators are completely an organic solutions that changes color in the solution we added them to it due to the change in PH.....they are used to determine the equevelant point and the end point in titration
What colour does a universal indicator change to when it is mixed with an acid?
red
An indicator does which one of the following in the presence of acids and bases?
Indicators can be used to determine if a substance is a acid or a base because of the reaction that occurs between the substance and the indicator. This creates a color change in the indicator (depending on which indicator you use). If it is a universal indicator, the substance may change from deep red to violet. If it is a litmus indicator, it will only turn either red or blue.
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 colour does a universal indicator change to when it is mixed with a strong acid?
green or blue
How do you find the pH of an indicator?
Put a drop of universal indicator solution and observe the color change. Look online for the table.

Universal indicator is a solution that changes what in an acidic or alkali solution?
Universal indicator doesn't change anything in an acidic or alkali solution. All universal indicator does is show how acidic or alkaline a solution is (red being acidic, green being neutral and blue being alkali)
What colour does universal indicator change to if chlorine water is added?
Bright red and the colourless
What colour does a universal indicator change to when it is mixed with ethanol?
U should no this r u stupid

Why does the universal indicator change colour it had put vinegar?
The pH of 5% vinegar is between 2 and 3. The color of universal indicator in that range is reddish-orange.
