Why does hydrochloric acid change phenolphthalein purple to colorless?
we know that hcl is an acid and acids change purple phenolphthalein to colourless. So HCL changes purple phenolphthalein to colourless
What happens when mix HCl and iron powder?
Fe + HCl --> FeCl2 + H2
When you mix a few drops of phenolphthalein solution to a beaker of pure water mixed with calcium hydroxide what happens?
the colour changes to pink
What happens when water is added to phenolphthalein?
Phenolphthalein dissolves in water to get a clear transparent solution.
In HCl and NaOH titration which indicator is used?
Phenolphthalein indicates red for acids and blue for bases.
What happens when you mix calcium hydroxide and phenolphthalein?
It changes colors

What happens when you mix sodium bicarbonate solution and phenolphthalein?
it turns into a pinkish red color
What happens when you mix Sodium hydroxide and phenolphthalein?
it will turn pink. phenophathaline turns pink in alkaline ph

In HCl and NaOH titration which indicator is used?
Phenolphthalein indicates red for acids and blue for bases.
What would you mix an alkali or acid with to get a coloured substaince?
You could mix an acid or alkali with an indicator such as methyl orange or phenolphthalein. Phenolphthalein is colorless in an acidic medium and pink in an alkaline one.
What happens when you mix Hydrochloric acid with ammonia?
A white solid Ammonium chloride is formed, HCl + NH3 -----> NH4Cl
What is the equation for neutralization of hydrochloric acid and phenolphthalein?
Phenoxide and Hydrochloric acid: C6H5O-Na+ + HCL ----> C6H5OH + NaCl
Why methyl orange is used instead of phenolphthalein in hcl and naoh titration?
This is so since the pH at the end point of Phenolphthalein is 9.1 and methyl orange is 3.7. For a strong acid strong base titration which the end point is between 3-11 phenolphthalein is used
