How do you dilute a 10 M H2SO4 to 1M H2SO4?
Remember M1V1=M2V2, where M is molarity and V is volume. M1/M2=V2/V1, 10/1=v2/v1, For diluting the acid, we can add acid to water. So, assuming that 10M H2SO4 is having 1ml of water, we should add 1M of H2So4 to 10ml of water.
What substance would you add to NaHCO3(aq) to form a buffer solution?
You would add a weak acid, like acetic acid (CH3COOH), to NaHCO3(aq) to form a buffer solution. The weak acid will react with the bicarbonate ion in NaHCO3 to maintain a stable pH.
How to make 4.5 m H2SO4?
To make 4.5 M H2SO4 from concentrated sulfuric acid (98% H2SO4), you would need to dilute it with water. Calculate the volume of concentrated sulfuric acid needed based on the final volume desired, then add water to reach the total volume. Always remember to add acid to water slowly and carefully to avoid splashing or overheating.
What substance would you add to NaHCO3 to form a buffer solution?
You could add a weak acid or a weak base to NaHCO3 to form a buffer solution. Examples of substances that could be added include acetic acid (CH3COOH) or ammonia (NH3). Buffer solutions help resist changes in pH when small amounts of acid or base are added.
Why do you add H2SO4 instead of HCL in redox titration?
H2SO4 is preferred over HCl in redox titrations because HCl can release Cl2 gas during the reaction, which can interfere with the titration results. H2SO4 provides the necessary acidic conditions for the redox reaction without introducing additional complications.

What happens if you add magnisium ribbon to sulphic acid?
Sulfuric acid? Mg + H2SO4 -> MgSO4 + H2 You produce magnesium sulfate ( a salt ) and hydrogen gas. ( you should see many bubbles of the hydrogen gas in solution )
What are the products when you add H2SO4 to NaOH?
Salt plus Water. In this case the salt would be Sodium Sulphate.
Why the reaction between sulfuric acid and water is exothermic?
It spits quite alot if you add H2SO4 to H2O

What happens when you add calcium oxide and sulphuric acid?
When calcium oxide (CaO) is added to sulfuric acid (H2SO4), they undergo a chemical reaction to form calcium sulfate (CaSO4) and water (H2O). This reaction is an example of a neutralization reaction, where an acid and a base react to produce a salt and water.
What you add firstly in carbohydrate solution either H2SO4 or 1-naphthol?
1-naphthol is added first to a carbohydrate solution to detect the presence of carbohydrates. Then, sulfuric acid (H2SO4) can be added to the solution to further test for specific carbohydrates based on color changes or precipitation.
What is the formula of the conjugate acid for base rm SO 42?
The conjugate acid of the sulfate ion (SO4^2-) is sulfuric acid (H2SO4). To form the conjugate acid, you add a proton (H+) to the base molecule.
