What happens when you mix Sodium hydroxide and phenolphthalein?
When you mix sodium hydroxide and phenolphthalein, you will observe a color change. Phenolphthalein is commonly used as a pH indicator, turning pink in basic solutions (such as sodium hydroxide) and colorless in acidic solutions. This color change is a result of the chemical reaction between the sodium hydroxide and phenolphthalein molecules.
Is adding phenolphthalein to sodium hydroxide a chemical change?
No, adding phenolphthalein to sodium hydroxide is a physical change because it only involves mixing two substances together. A chemical change would involve a new substance being formed through a chemical reaction, which does not occur in this case.
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?
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?
React iron iii nitrate and sodium hydroxide?
When iron (III) nitrate reacts with sodium hydroxide, it forms iron (III) hydroxide and sodium nitrate. The balanced chemical equation for this reaction is: Fe(NO3)3 + 3NaOH → Fe(OH)3 + 3NaNO3. Iron (III) hydroxide is a brown solid that forms as a precipitate in this reaction.
What is the chemical equation for Pyrogallic acid an sodium hydroxide?
Pyrogallic acid and sodium hydroxide is used to provide anaerobiosis.

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 colo is PHTH in Sodium Hydroxide?
Phenolphthalein turns pink in basic solutions
Is physical or chemical reaction takes place when sodium hydroxide mixed with water?
It is a physical change. The sodium hydroxide dissolves, but it is still sodium hydroxide.
How does sodium oxide and water make sodium hydroxide?
When sodium oxide reacts with water, it undergoes a chemical reaction to form sodium hydroxide. This reaction involves the hydration of sodium oxide, which results in the formation of sodium hydroxide as a product. The chemical equation for this reaction is: Na2O + H2O → 2NaOH.
Is iron chloride and sodium hydroxide a physical or chemical change?
The reaction between iron (III) chloride and sodium hydroxide is a chemical change as new substances are formed. Iron (III) hydroxide and sodium chloride are produced as a result of the reaction.
Why does sodium hydroxide and phenolphthalein mixture turn clear when carbon dioxide is added?
Carbon dioxide dissolves in the aqueous solution to produce carbonic acid. The carbonic acid dissociates to produce the carbonate ion and two protons. The protons reacts with the hydroxide provided by the already dissociated sodium hydroxide to produce water. The sodium carbonate is fairly soluble and stays in solution. Since the hydroxide ion is depleted, the phenolphthalein reverts from pink to clear as it does in solutions with a pH less than 8.3.
Why is phenolphthalein indicator used in the titration of oxalic acid against sodium hydroxide?
Phenolphthalein is used as an indicator in the titration of oxalic acid against sodium hydroxide because it undergoes a color change at the pH region where the reaction between oxalic acid and sodium hydroxide is neutralized. Oxalic acid is a diprotic acid, meaning it requires two equivalents of sodium hydroxide to be fully neutralized. Phenolphthalein changes color at a pH of around 8.2-10, which is ideal for indicating the endpoint of the titration.
What is the chemical equation of ethanoic acid reacting with sodium hydroxide?
The chemical equation for the reaction between ethanoic acid (acetic acid) and sodium hydroxide is: CH3COOH + NaOH → CH3COONa + H2O This reaction is a neutralization reaction that forms sodium acetate and water.
What is sodium oxide combines with water to make sodium hydroxide?
When sodium oxide reacts with water, it forms sodium hydroxide by the following chemical equation: Na2O + H2O -> 2NaOH. This reaction releases heat and is highly exothermic. Sodium hydroxide is a strong base commonly used in industries such as water treatment, soap making, and chemical production.
What would happen if you added phenolphthalein to sodium hydroxide?
Phenolphthalein is a pH indicator that turns pink in basic solutions. When added to sodium hydroxide, which is a strong base, the phenolphthalein will turn pink to indicate that the solution is basic.
