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.

Is an indicator's reaction in acids and bases a chemical change?
Yes
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
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 word describes chemicals which change colour in acids and alkalis?
acid-base indicators for all pHs: universal indicator for pH testing in general: indicator
Effect of methyl red to acid and base?
It's an indicator that turns red with acids and yellow with bases (though I prefer to use the term alkalis).Actually, that answer is not strictly true because it will turn yellow at a pH of slightly less than pH 7 (neutral) so some weak acids will appear to be alkaline with this indicator.
Is an indicator's reaction in acids and bases a chemical or physical change?
That is a chemical change.
Is an indicator's reaction in acids and bases a chemical change?
Yes
What substance is like litmus that will change color in acids acids alkali?
This substance is called a pH indicator.

What three indicators would make a good universal indicator?
Well, there are the three main ones which are neutral, acids, alkaliHope this helped :)
Is pH an indicator of acids and bases?
yes, the pH above 7 is basic and below 7 is acidic. Neutral pH id 7.
What word describes chemicals which change colour in acids and alkalis?
acid-base indicators for all pHs: universal indicator for pH testing in general: indicator
What colour an alkali comes out with a universal indicator?
Blue/Violet/Indigo . depending on the strength of the alkali. Water (neutral ) is green Acids ' Red/Orange/Yellow.
Why is a indicator's reaction in acids and bases a chemical change?
Indicates whether the substance is an acid or alkali.
Why is red cabbage indicator not a good experiment to measure buffering capacity?
A buffer absorbs or releases excess hydrogen ions, making the solution hold at a steady pH. Since red cabbage indicator makes a good pH indicator, it has a neutral pH. any amount of acids or bases added would change the pH of the red cabbage juices. If it made a good buffer, it would not make a good pH indicator.
Does sugar just neutralise acids in taste or does it actually change the pH of food?
sugar has a neutral pH, so it doesn't really neutralize acids.
