What is the effect of dilute HCL on colour of blue litmus?
Dilute HCl turns blue litmus paper red. This is because the HCl solution is acidic, causing a color change in the blue litmus paper indicating the presence of an acid.
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 the chemical formula for dilute hydrochloric acid?
The chemical formula for dilute hydrochloric acid is HCl.
What is the symbol for dilute hydrochloric acid?
The chemical symbol for dilute hydrochloric acid is HCl.
What is the refractive index of dilute HCl?
The refractive index of dilute HCl depends on its concentration and temperature. Generally, for low concentrations and room temperature, the refractive index of dilute HCl is around 1.33.
What is the color of phenolphthaline in dilute HCl?
it is colour less only b`coz the colour of phenolpthaline is pink then we dilute in hcl and hcl is colour less that`s why it is colour less

Does ZnCl2 react with dilute HCl?
No, ZnCl2 does not react with dilute HCl because ZnCl2 is already a product of the reaction between zinc metal and HCl. So, no further reaction occurs when ZnCl2 is added to dilute HCl.
Why is dilute hcl preferred to dilute h2so4 in CO2?
dicks
What is the equation of sodium hydroxide with phenolphthalein with hydrochloric acid?
The equation for the reaction between sodium hydroxide (NaOH) and hydrochloric acid (HCl) using phenolphthalein indicator is: NaOH + HCl → NaCl + H2O Phenolphthalein is a pH indicator that turns pink in basic solutions and colorless in acidic solutions.
Why does hydrochloric acid change phenolphthalein purple to colorless?
Hydrochloric acid is a strong acid that neutralizes the alkaline properties of phenolphthalein, turning it colorless. This reaction occurs because the acid donates hydrogen ions, causing a shift in the pH balance and resulting in the loss of the pink or purple color in phenolphthalein.
Is dilute HCl a acid or base?
It is an acid.
In HCl and NaOH titration which indicator is used?
Phenolphthalein is commonly used as an indicator in the titration of hydrochloric acid (HCl) with sodium hydroxide (NaOH). Phenolphthalein changes color from colorless to pink at the endpoint of the titration when all the acid has been neutralized by the base.
