What indicator has no color at all?
phenolphthalien when added to an acidic solution has a colourless indicator. but shows pink colour for basic solution.
What color of universal indicator in agar solution?
It depends on the pH.
When do you know endpoint of titration?
when the colour of the indicator used is the color it should be in neutral
What is auto indicator?
Auto indicator is a substance which remaining in a titration as a standard solution or a distandard solution shows ending point of a reaction by changing its color.
How many pH units change are usually required for an indicator to undergo a color transition?
It depends on the sensitivity of the indicator you are using. There should be a guide with the indicator you are using. Litmus paper, which is the most common form of pH indicator, will change fairly constant across the pH scale, but a neutral (pH 7+/- 0.5 about) solution will normally not cause a change.
What color will the indicator be in a neutral sodium hydroxide?
the indicator will be the pale colors of green :)
What pH colour is a neutral?
The color is green for the universal indicator.
What color is a neutral solution?
Any color is possible.
What is the indicator and color change for a positive test for glucose?
Benedict solution is the chemical indicator for simple sugars.
What indicator has no color at all?
phenolphthalien when added to an acidic solution has a colourless indicator. but shows pink colour for basic solution.
What color of universal indicator in agar solution?
It depends on the pH.
When do you know endpoint of titration?
when the colour of the indicator used is the color it should be in neutral
Why is phenolphthalein indicator used?
Phenolphthalein is used as an indicator because the color of the solution is changed according to pH.
What is auto indicator?
Auto indicator is a substance which remaining in a titration as a standard solution or a distandard solution shows ending point of a reaction by changing its color.
Why did the purple indicator turn blue in plain water and pink in water with vinger added?
This is because most likely, the indicator was a PH indicator, plain water has a neutral to low Ph indicated by blue. Whereas when vining air is added it increases the acidity of the solution as indicated by the pink color.
What is the solution of NaOH in methyl orange indicator?
Methyl orange shows yellow color in an NaOH solution.
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.
