What would be the color of a solution containing hydrochloric acid and phenolphthalein?
Answer: Phenolphthalein will be colourless in 0.1M HCl solution.
What will be the colour change when phenolphthalein is added to hydrochloric acid in sodium hydroxide?
Answer: When few drops of phenolphthalein are added to dilute a dilute solution of sodium hydroxide a pink colour. The colour of dilute solution of Sodium hydroxide turns pink or adding Phenolphthalein as NaOH is a base .
What is the colour of phenolphthalein in dilute HCl and dilute NaOH?
Phenolphthalein remains colourless in neutral or acidic solution but turns out magenta or pink in basic solutions. When it is added to NaOH, the solution has the colour of pink since sodium hydroxide is a strong base.
What happens when you mix sodium hydroxide and phenolphthalein and hydrochloric acid?
Explanation: When the sodium hydroxide, which is a base, is mixed with phenolphthalein, it turns pink. This happens because the base is neutralized in an acid solution, which causes the indicator to become colorless. All of the base is neutralized by the citric acid.
What is the colour of dilute hydrochloric acid?
| Sr. No. | Sample Solution | Colour appeared on pH paper |
|---|---|---|
| 1. | Dilute HCl | Red |
| 2. | Dilute NaOH solution | Purple |
| 3. | Dilute Ethanoic Acid solution | Yellow |
| 4. | Lemon Juice | Orange |
Is there any colour change for the reaction mixture?
Explanation: The colour of solution is pink as phenolphthalein turns pink when added to base. After adding acid the mixture becomes colourless because acid has neutralized the effect of base and phenolphthalein is colourless in acid. Neutralization reaction occurs where acid neutralizes base.
