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 will universal indicator paper go if dipped into ammonia solution?
blue because it is a weak alkali
Is alkali soluble in water?
you can find out if a substance is an acid or alkali by adding universal indicator
The color of methylorange indicator in a neutral solution?
an universal indicator paper tells you how acid or how alkali it is acid - red alkali - blue neutral - green
Is sugar acid or alkali?
sugar is a acid when dipped or mixed in universal indicator...............
What is the material used to remove an indicator from a neutralized solution how does this work?
it is universal indicator with mixture of alkali

How does a acid-alkali indicator indicates?
The pH of a solution.

What color is the universal indicator in an alkali?
Many soluble dyes change their color with changes in pH (a measure of the concentration of acid in a solution). Such dyes may be used to indicate when the acid (base) in a solution has been neutralized by addition of an equal amount of base (acid). Each indicator dye has a particular range of pH for which it is useful. pH test strips and papers often incorporate two or more dyes to extend the range of pH over which they can be used. The best indicator dyes are strongly colored (so that only small amounts are needed), undergo an easily seen change with pH (either from one color to another, or from clear to colored), are nontoxic, and are chemically stable.
What would you use to show when an acid has completely reacted with an alkali?
A pH indicator: the color is changed at the end of the reaction, when the solution become alkaline.
What effect does and alkali have on an universal indicator?
It turns the universal indicator purple or blue.
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 is a hydroxide solution a acid or alkali?
Alkali
