The neutralization of hydrochloric acid with phenolphthalein does not involve an equation. Phenolphthalein is a pH indicator that changes color at a certain pH range (8.2-10), making it useful for determining the endpoint of a titration involving an acid-base reaction like the neutralization of hydrochloric acid with a base.

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.
What happens if phenolphthalein solution is added in hydrochloric acid?
If phenolphthalein solution is added to hydrochloric acid, it will remain colorless since the pH of hydrochloric acid is too low for phenolphthalein to change color. Phenolphthalein typically turns pink in a basic solution but does not show a color change in acidic conditions.
Why is phenolphthalein colorless in hydrochloric acid?
Phenolphthalein is colorless in acidic conditions, such as hydrochloric acid, because it undergoes protonation, forming a colorless form of the molecule. This protonation reaction alters the structure of phenolphthalein, preventing it from exhibiting a color change.
Phenolphthalein change color when mixed with hydrochloric acid?
Phenolphthalein is a pH indicator that changes color in response to a change in pH. When mixed with hydrochloric acid (a strong acid), phenolphthalein will turn colorless due to the decrease in pH, indicating an acidic solution.
Which balanced equation represents the neutralization reaction involving HCl and LiOH?
The balanced equation for the neutralization reaction between hydrochloric acid (HCl) and lithium hydroxide (LiOH) is: HCl + LiOH -> LiCl + H2O
What is the equation of sodium hydroxide with phenolphthalein with hydrochloric acid?

Equation for neutralization of triethylamine with HCl?
The balanced chemical equation for the neutralization of triethylamine (C6H15N) with hydrochloric acid (HCl) is: C6H15N + HCl --> C6H16N+Cl-
What is the equation for neutralization of sodium hydroxide with hydrochloric acid?
NaOH(aq) + HCL(aq) = NaCl(aq)l + H2O(l)
What colour does hydrochloric acid turn phenolphthalein?
Hydrochloric acid does not change the color of phenolphthalein. Phenolphthalein is typically used as an acid-base indicator, turning from colorless to pink in the presence of a base.
What is the reaction of hydrochloric acid and phenolphthalein?
Hydrochloric acid (HCl) is a strong acid that will react with phenolphthalein, a pH indicator, causing it to turn colorless in acidic conditions. This reaction occurs due to the change in pH of the solution, which shifts the equilibrium of the phenolphthalein molecule leading to its color change.
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.
Which word describes the reaction between hydrochloric acid and sodium hydroxide?
Neutralization
What is the complete neutralization of potassium hydroxide with hydrochloric acid?
The complete neutralization of potassium hydroxide (KOH) with hydrochloric acid (HCl) results in the formation of potassium chloride (KCl) and water (H2O). The balanced chemical equation for this reaction is: KOH + HCl -> KCl + H2O.
