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.

How is cooking similar to an experiment?
Just like a scientific experiment, cooking involves performing different functions on various ingredients that may be combined by mixing or chemically changing them into a new substance, using heat or some other catalyst. You have to get the amounts of each item right and you have to perform actions on those items in specific, repeatable ways, for the right amount of time. Very scientific, indeed!
Why is ferric chloride only used in catalytic amounts?
Iron chloride is only used in catalyst amounts because it is highly reactive and will release hydrogen which is highly flammable.
What role does iron oxide play in the Haber process?
the role it plays is by using an iron oxide catalyst eliminates the need for excessively high temperatures and without the catalyst the production of significant amounts of ammonia is too slow to be economical
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?
substances
What is a substance that resists a pH change when small amounts of acid or base are added?
buffer
Is a catalyst required in small amounts?
yes it is required in small amounts. The lesser the catalyst, the better is its efficiency.
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.

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.
