Is a catalyst a substance that maintains the pH even when the amounts of acid or base are changing?
No, I think what you're thinking of is a 'buffer' or more correctly a 'buffering agent'.
A catalyst is a chemical substance which allows a chemical reaction to occur between two or more other chemicals (often at a quicker speed and/or with a lower amount of energy needed) because of the presence of the catalyst. The other thing that is important is that a catalyst is not used up in the course of the chemical reaction.
I hope that is helpful.

Why is air a pure substance?
Air is considered a pure substance because it is a homogeneous mixture of gases, mainly nitrogen, oxygen, carbon dioxide, and trace amounts of other gases. Each component of air retains its unique chemical properties and cannot be separated by physical means without changing the composition of air.
Why is ferric chloride only used in catalytic amounts?
Ferric chloride is used in catalytic amounts because it can regenerate during the reaction, making it a catalyst rather than a reagent. Using it in small quantities is cost-effective and minimizes waste disposal issues associated with excess reagent.
What describes the dissolved substance in a solution?
The dissolved substance in a solution is known as the solute. It is typically present in smaller amounts compared to the solvent, which is the substance in which the solute is dissolved. The solute and solvent together make up a solution.
What is an organic substance required in small amounts in the diet?
You may be thinking of the various vitamins.
When equal amounts of energy are transferred to or from equal masses of different substance the substance will undergo different changes in temperature because of their different?
specific heat capacities. The substance with the lower specific heat capacity will experience a greater change in temperature compared to the substance with a higher specific heat capacity.
What is cactalyst?
A catalyst is a substance, usually used in small amounts relative to the reactants, that modifies and increases the rate of a reaction without being consumed in the process.
A substance usually used in small amounts relative to the reactants that modifies and decreases the rate of a reaction without being consumed in the process?
Poison - the opposite to catalyst
What are the two attributes of a catalyst?
A catalyst must change the rate of a chemical reaction. It must be unchanged at the end of the reaction.
Is a catalyst required in small amounts?
Yes, a catalyst is typically required in small amounts to increase the rate of a chemical reaction without being consumed in the process. It works by providing an alternative reaction pathway with lower activation energy, allowing the reaction to proceed faster.
What is the movement of a substance from where it is in large amounts to where it is in small amounts called?
diffusion
Why is catalyst effective in small amounts?
Catalysts are effective in small amounts because they facilitate chemical reactions by lowering the activation energy required for the reaction to occur, allowing reactants to convert to products more easily. They are not consumed in the reaction, meaning a single catalyst molecule can participate in multiple reaction cycles. This efficiency allows a small quantity of catalyst to influence a large number of reactant molecules, enhancing the overall reaction rate without the need for large amounts of the catalyst itself.
How is Paris changing and why?
Paris is changing due to the amounts of tourists and the size of the area it covers
Which is not a fact for why your body needs calcium in significant amounts?
calcium maintains healthy red blood cells
Why is air a pure substance?
Air is considered a pure substance because it is a homogeneous mixture of gases, mainly nitrogen, oxygen, carbon dioxide, and trace amounts of other gases. Each component of air retains its unique chemical properties and cannot be separated by physical means without changing the composition of air.
What is the difference between substance and a pure substance?
A pure substance is one which contains only that substance and nothing else. An impure substance contains other substances in varying amounts.
What is Substance that release useful amounts of energy when they burn?
Fuels
Why is ferric chloride only used in catalytic amounts?
Ferric chloride is used in catalytic amounts because it can regenerate during the reaction, making it a catalyst rather than a reagent. Using it in small quantities is cost-effective and minimizes waste disposal issues associated with excess reagent.
