Is hydrochloric acid and phenolphthalein a chemical change?
When HCl and phenolphthalein are mixed, a chemical reaction occurs leading to a change in the color of the solution (from pink to colorless). This is a chemical change as new substances are formed with different properties than the original substances.
When you mix a few drops of phenolphthalein solution to a beaker of pure water mixed with calcium hydroxide what happens?
The phenolphthalein solution will turn pink in the presence of the basic calcium hydroxide solution. This color change indicates the presence of a base. This reaction is commonly used as an indicator for determining the endpoint in acid-base titrations.
What color does phenolpthalein turn in the presenc of an acid?
Phenolphthalein only gives colour to bases with a pH above approximately 8.2-10. Then it gives a pink colour. As HCL is a strong acid it becomes colourless.
What is chemical which mixed with caustic soda becomes pink?
Phenolphthalein is the indicator that turns pink in alkaline solutions it WILL NOT show any colour in an acid environment!!
What gas was produces when zinc and hydrochloric acid were mixed?
Hydrogen gas was produced when zinc and hydrochloric acid were mixed. This is because when zinc reacts with hydrochloric acid, hydrogen gas is released as one of the products of the reaction.
Phenolphthalein change color when mixed with water?
Yes, the color become pink.

What colour changes will appear when phenolphthalein is mixed with sodium chloride solution?
When phenolphthalein is mixed with sodium chloride solution, no color changes will occur. Phenolphthalein is a pH indicator that changes color in response to pH levels, while sodium chloride (table salt) does not significantly affect the pH of a solution.
What is the colour of zinc ions mixed with ammonia in phenolphthalein indicator?
The phenolphthalein indicator is pink in basic solutions.
What does phenolphthalein do when mixed with salts?
The Phenophtalein will remain clear.
When you mix a few drops of phenolphthalein solution to a beaker of pure water mixed with calcium hydroxide what happens?
The phenolphthalein solution will turn pink in the presence of the basic calcium hydroxide solution. This color change indicates the presence of a base. This reaction is commonly used as an indicator for determining the endpoint in acid-base titrations.
What are the two transparent liquids when added gives a pink liquid?
When colorless phenolphthalein is added, upon mixing it will turn a beautiful shade of pink. This chemical reaction occurs when a base such as ammonia is mixed with an acid like hydrochloric acid.
Is Hydrochloric acid mixed with sodium bicarbonate a physical or chemical change?
It is a chemical change. An acid and a base reacting to form a new substance.
What color does phenolpthalein turn in the presenc of an acid?
Phenolphthalein only gives colour to bases with a pH above approximately 8.2-10. Then it gives a pink colour. As HCL is a strong acid it becomes colourless.
Why does petrol change color when mixed with iodine solution?
Petrol changes color when mixed with iodine solution due to covalent bonding.
When water and hydrochloric acid are mixed why does the pH differ when more acid is mixed?
because pH is the measure of how much acid it contains it would change if you added more
What color does salt turn when mixed with liquid indicator?
When salt is mixed with a liquid indicator, it may not change color immediately. The liquid indicator's color change is usually due to a change in pH levels rather than the presence of salt. Salt does not typically cause a color change in liquid indicators.
