Why does addition of H2SO4 stop reactions?
H2SO4 is an acid, so when you add that to the catalase reactions, the pH drops below where the catalase can function. Acids have lower pH and therefore the catalase can no longer function, so the reaction stops.
What is the role of sulphuric acid in the reaction?
Sulfuric acid can act as a catalyst in some reactions by providing protons that can initiate chemical transformations. It can also function as a dehydrating agent, removing water molecules from reactants to promote certain reactions. Additionally, sulfuric acid can serve as a source of sulfate ions in reactions where sulfate compounds are needed.
Why does the reaction between calcium carbonate and sulphuric acid stop?
The reaction between calcium carbonate and sulfuric acid stops when all the calcium carbonate has been consumed, forming calcium sulfate, water, and carbon dioxide. Once all the reactants have been used up, the reaction can no longer proceed.
Why does heat and acid cause a catalase to stop functioning?
Catalase is a protein and proteins can de-nature or change shapes when exposed to heat. Acid is very corrosive and so my guess would be that acid would just eat away at the protein and cause the protein to lose major parts needed to function
What salt is created when you mix sulfuric acid potassium hydroxide?
K2SO4, potassium sulfate, when 1 mole sulfuric acid is added to 2 moles potassium hydroxideorKHSO4, potassium hydrogen sulfate (-bisulfate), when 1 mole sulfuric acid is added to 1 mole potassium hydroxide

What would the reaction rate do if another substance that binds to the active site of catalase was added?
If another substance binds to the active site of catalase, it could potentially inhibit or slow down the enzyme's activity. This could decrease the rate of reaction catalyzed by catalase, as the binding of the other substance may interfere with the enzyme's ability to bind with its substrate and convert it to products.

Why does the reaction stop in baking soda and vinegar?
The reaction will stop when one or other of the reagents are used up. The acetic acid concentration of vinegar varies at around 5 to 10%. When used up in the reaction, then the reaction will stop.
How does the time require for the bubbles to stop reflect the amount of catalase activity in the solutions?
The longer it takes for the bubbles to stop forming, the more catalase there is present, assuming that there is enough peroxide (H2O2) to keep the catalase going.
Why did the fizzing stop when he countied to add the acid?
The fizzing stop when the chemical reaction is totally finished.
Why does the reaction stop between magnesium and hydrochloric acid?
The reaction between magnesium and hydrochloric acid stops when all the magnesium has reacted with the acid to form magnesium chloride and hydrogen gas. Once all the magnesium has been consumed in the reaction, there is no more magnesium to react with the acid, leading to the reaction coming to a halt.
What is the function of sulphuric acid in the experiment of enzyme activity?
H2SO4 is used to denature the enzyme and stop the reaction instantly. by adding H2SO4,it will prevent further reaction of the enzyme onto the substrate and the rate of enzyme reaction can be measured in the specific time
Why sulphuric acid is not used in preparation of carbon dioxide from calcium carbonate?
Sulfuric acid is not suitable for preparing carbon dioxide from calcium carbonate because it reacts with calcium carbonate to form calcium sulfate, water, and carbon dioxide. This reaction can be impractical and difficult to control because it produces an additional product (calcium sulfate). It is more efficient to use a weaker acid, such as hydrochloric acid, which will react only with the calcium carbonate to produce carbon dioxide and water.
