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?
Adding more sodium hydroxide will increase the concentration of the reactant in the reaction, leading to more successful collisions between particles and thus speeding up the reaction. This happens because there are more particles available to react with hydrogen chloride, resulting in a higher reaction rate.
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?
The chemical equation for the reaction between pyrogallic acid and sodium hydroxide is: C6H3(OH)3 + 3NaOH -> C6H6O3 + 3NaOH
