When you add an acid to an alkali it changes to a neutral which colour change would this show with an indicator?

It depends on the indicator and there are quite a few. Methyl Red, Methyl orange and Phenolphthalein are 3 such acid-base indicators. If phenolphthalein is used as the indicator and added to the base it would immediately turn red/pink. As acid is titrated in, the red/pink will disappear and go colorless.

Why is a indicator's reaction in acids and bases a chemical change?
Indicates whether the substance is an acid or alkali.
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.
What is a indicator organisms?
Indicator organisms are organisms that are sensitive to changes in the environment. When populations of indicator species changes, it can signal a change in the environment that will eventually effect other species as well.
What is organic indicator?

Which indicator could be used to identify a neutral solution?
there is no such indicator.the only way is to add the acidic and basic indicators ,if it does not change the colour of the solution then it is neutral.
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)

When you put an alkali and Universal Indicator in a test tube what colour does it go?
When an alkali is added to a test tube containing Universal Indicator, it typically turns the indicator solution a dark green or blue color. This is because Universal Indicator is a mixture of different pH indicators that show a range of colors from red (acidic) to green (neutral) to blue or purple (alkaline). The specific color change observed may vary depending on the concentration and type of alkali used.
What color change does each indicator show to represent acids bases and neutral?
There are far too many indicators to give them all. Litmus is blue in alkali, red in acids and an in-between colour often called claret when neutral. Universal indicator is red in strong acids, blue in strong alkalis and different colours in between depending on the brand.
What changes color at the endpoint of titration?
change in pH, changes the colour (of the indicator)
What substance is like litmus that will change color in acids acids alkali?
This substance is called a pH indicator.
What is a indicator organisms?
Indicator organisms are organisms that are sensitive to changes in the environment. When populations of indicator species changes, it can signal a change in the environment that will eventually effect other species as well.

What indicators can be used in titration?
Acid Alkali Indicator Details Strong Strong Methyl Orange pipette alkali, and burette acid (change from yellow to light pink when neutralised) Weak Strong Phenolphthalien pipette acid, and burette alkali (change from colouless to salmon pink when neutralised) Strong Weak Methyl Orange pipette alkali, and burette acid (change from yellow to light pink when neutralised) Acid Alkali Indicator Details Strong Strong Methyl Orange pipette alkali, and burette acid (change from yellow to light pink when neutralised) Weak Strong Phenolphthalien pipette acid, and burette alkali (change from colouless to salmon pink when neutralised) Strong Weak Methyl Orange pipette alkali, and burette acid (change from yellow to light pink when neutralised)
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.
Is an indicator color change an acid or base?
depends on the indicator used. in case of red litmus... changes to blue for basesand no change in acids blue litmus - changes to red in acids, no change in bases phenolpthelin - changes to pink in bases, no change in acid methyl orange - changes to red in acids and yellow golden in bases
