How indicators works?
pH indicators change their color according to the pH of a solution.
What is the colour of phenolphthalein in salt water?
It will turn purple
Describe the major limitation of the Arrhenius theory of acids and bases?
Arrhenius's theory was limited by the fact that hydrochloric acid is neutralised by both sodium hydroxide solution and ammonia solution. In both cases, you get a colourless solution which you can crystallise to get a white salt - either sodium chloride or ammonium chloride.
What is the colour of phenolphthalein in aspirin solution?

How do I measure the pH of colourless solution?
hey
What colour is Sulfuric Acid in water?
Sulphuric Acid is colourless. Water is colourless. When dissolved together, the solution remains colourless.
What is the colour of magnesium nitrate solution?
Pure magnesium sulfide (MgS) is a white crystalline solid at room temperature.
What compound changes color when used to determine the pH of a substance?
There are a variety of indicators used to determine change in pH. Different indicators change during certain ranges of pH. For example, phenolphthalein turns from clear to pink in a basic solution (approximately 7.8 to 9). There are universal indicators that cover the whole pH scale.
The aqueous solution of zinc sulphate is?
Colourless, icepose.
What characteristics limit the usefulness of indicators?
Chemical indicators measure the pH directly Chemical indicators are highly expensive They must be chosen for a specific pH range Chemical indicators cannot determine the exact value of pH of the solution
How can you found out if somthing is an indidcator?
if something is and indicator, then it will be able to proove to you wether a substance is acid or alkali. here are some common lab indicators used to determine the Ph value of some substances. remember, pH 1-6 is acid ph7 is neutral and pH 8-14 is alkali -Litmus paper is red in a neutral solution, red in an acid and blue in an alkaline solution -Universal indicator is is green in a neutral solution, red, orange or yellow in an acid and blue or violet in an alkali -Phenolpthalein is colourless in a neutral solution, colourless in an acid and pink inn an alkal -Screened methyl orange is orange in a neutral solution, red for pH below 3.6, orange for pH above 3.6 and yellow in an alkaline solution
What is acid-base indicators?
These indicators change the color depending on the pH of the solution.
How indicators works?
pH indicators change their color according to the pH of a solution.
How can you tell if a colourless liquid is an acid or an alkali?
For an acid, the solution remains colourless or unchanged. For an alkali, it would turn fuschia.
