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.
A base is a compound that turns litmus blue and is often found in soaps and detergents?
true
If you add alkali to water what colour would the water be?
Alkalis are bases dissolved in water. They do not have specific colours and are often colourless liquids.Indicators are used to determine the strength of an acid or alkali and change colour when exposed to the liquid.Look at Universal Indicator Solution.
What is an indicator for acid and bases?
There are three types of substances acids, bases, and neutrals. The properties of an acid include they are sour, have a PH of less then 7, corrosive to skin, contains hydrogen, and reacts to litmus paper.
Is paper a physical or chemical change?
Litmus is a water-soluble mixture of different dyes. It is often absorbed onto filter paper to produce one of the oldest forms of pH indicator, used to test materials for acidity. Blue litmus paper turns red under acidic conditions and red litmus paper turns blue under basic (i.e. alkaline) conditions, with the color change occurring over the pH range 4.5 - 8.3. Neutral litmus paper is purple in color. Litmus can also be prepared as an aqueous solution that functions similarly. Under acidic conditions the solution is red, and under basic conditions the solution is blue. So the litmus paper turning blue or red is a "Chemical Change".
Why is water used as the universal indicator?
Water is NOT Universal Indicator. Water is often referred to as a Universal Solvent as a large number of substances are soluble in it. Universal Indicator is a chemical agent that can be used to test the pH of a liquid.

Explain the work of phenophthaline and litmus paper?
It is an acid - base indicator. Often used in titrations, it turns colorless in acidic solutions and pink in basic solutions.. litmus paper color... Red in acidic solution n blue in alkaline solution
How can a pH indicator be useful?
pH indicator works as the range by alkalinity wether it's basic or acidic. Indicator properties are often found naturally in plants (eg. litmus). pH indicators are often just refined versions of various natural plant chemicals or synthesized versions of them.
Water is often called the universal?
The universal solvent
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.

Where can you buy litmus paper?
Litmus paper is used to test how acidic or basic a material is. Because gardeners often want to test the acidity of their soil, you can buy litmus paper in many gardening shops. Of course, it is also available in places that sell science supplies, and readily available from vendors on the internet.
