When a drop of phenolphthalein is added to solution a it turns pink solution A is?

(b) Solution A gives pink colour when a drop of phenolphthalein indicator is added, therefore A is a base.

When solution A is added to phenolphthalein it turns pink when solution B is added to phenolphthalein it turns Colourless mention the nature of A and B?

The solutio A is basic in nature and phenolphthalein has imparted pink colour to it. The solution B is of an acid which has ultimately made solution A colourless by neutralising its basic effect.

Which color will be obtained when a drop of phenolphthalein is added to sodium hydroxide solution?

When few drops of phenolphthalein are added to a dilute solution of sodium hydroxide a pink colour is produced.

What happens when you add phenolphthalein?

Phenolphthalein is often used as an indicator in acid–base titrations. For this application, it turns colorless in acidic solutions and pink in basic solutions.

What happens when phenolphthalein is added to water?

If phenolphthalein is added to water it may turn into pink colour indicating that water contains some impurities but if water is distilled one it will not show any change in colour as it’s pH is neutral…

When few drops of phenolphthalein is added to a dilute solution?

When few drops of phenolphthalein are added to a dilute solution hydroxide a pink colour is produced.

When a few drops of phenolphthalein is added to a solution having pH 10.5 then the colour?

Phenolphthalein turns pink(magenta) when it reacts with a solution having pH above 8.5.

When a few drops of phenolphthalein is added to a solution having pH 9 Then the colour?

Answer: When few drops of phenolphthalein are added to a dilute solution hydroxide a pink colour is produced.

When few drops of phenolphthalein are added?

When few drops of phenolphthalein are added to dilute solution of sodium hydroxide a pink colour is produced .

When a few drops of phenolphthalein is added to a basic solution then change the colour?

Phenolphthalein remains colourless in neutral or acidic solution but turns out magenta or pink in basic solutions.

What happens when a few drops of phenolphthalein is added to an acidic and basic solution?

Nothing will happen beacause: Phenolphthalein is an acid/base indicator. It is colorless when it is an acid and pink when it is a base.

What is the colour of phenolphthalein and sodium hydroxide?

In Acidic solution phenolphthalein is colourless but in basic it gives pink colour . They both are used as a pH indicator . When a few drops of phenolphthalein are added to a dilute solution of sodium hydroxide, pink colour is produced.

What happens when Phenolphthalein is added to water?

Phenolphthalein is an acid indicator,means when we add water (pH 7) to it,it ionises giving a pink colour. That pink colour is actually due to the phenolphthalein ion. Following is the ionisation reaction. H + is colourless and I n − (phenolphthalein ion) is pink coloured .

What is the use of phenolphthalein indicator in titration?

Phenolphthalein is often used as an indicator in acid–base titrations…. For this application, it turns colorless in acidic solutions and pink in basic solutions…. It belongs to class of dyes known as Phthalein dyes…. Phenolphthalein is slightly soluble in water and usually is dissolved in alcohols for use in experiments….

What happens when sodium hydroxide reacts with hydrochloric acid?

During this reaction, if there is a slight excess of sodium hydroxide (even a single drop), the pale pink colour will exist. On the other hand, if all the sodium hydroxide is neutralized with hydrochloric acid, and then a slight excess of acid is added, the solution will be colourless as it gets into an acidic pH.
