the solution will turn into pink(which will gradually fade afterwards because carbon dioxide is present in the air that neutralizes the color effect of the hydroxide..
C20H14O4+ NaOH → NaKC8H4O4 (aq)+ H2O (l)
A chemical reaction occurs between sodium hydroxide and hydrogen chloride. Adding more sodium hydroxide to the reaction causes it to speed up. If you add more of a reactant, such as sodium hydroxide, can it be considered a catalyst? Why or why not?
The actual process of adding it is not. However, a chemical change does occur immediately after the addition.
Sodium hydroxide is a base. And phenolphthalein is a pH indicator that changes color at around a pH of 8.4, so you can tell when your solution that endpoint.
You get Iron (III) Hydroxide and Sodium Nitrate. It is a double displacement chemical reaction...
The chemical formula of sodium hydroxide is NaOH. The chemical formula of ammonium chloride is NH4Cl. Any reaction between these substances in water solution.

It is a physical change. The sodium hydroxide dissolves, but it is still sodium hydroxide.

C6H13Na + H2O

Sodium Hydroxide does not undergoes chemical change with water. It just becomes dilute or aqueous.
Any chemical reaction occur.
Yes. Phenolphthalein can be used as an indicator for the titration of a weak acid (oxalic acid) against strong base (sodium hydroxide).
Phenolphthalein is the indicator to see if it is more acidic or more basic
The reaction is NaOH +HCl = NaCl +H2O Both sodium hydroxide and Hydrochloric are "used up".
The chemical formula of sodium hydroxide is NaOH. The chemical formula of ammonium chloride is NH4Cl. Any reaction between these substances in water solution.
