Which indicator is used in titration of naoh and h2so4?
Methyl orange
A 25.00ml sample of h2so4 requires 22.65 ml of the 0.550m naoh for its titration what was the concentration of sulfuric acid?
(25.00ml H2SO4)(H2SO4 M) = (22.65ml NaOH)(0.550M) = 0.4983M H2SO4
What is the colour change in the titration of KOH with H2SO4 using methyl orange as the indicator?
orange
What happen when KBr is heated with conc H2So4 acid?
Balanced equation formed: H2SO4 + 2KBr ==> 2HBr + K2SO4
What is ammonia sulphate?
It is a compound. It is formed by reacting NH3 and H2SO4.

How can you differentiate between H2SO4 and HNO3?
by adding AgNO3, ppt. is formed in h2so4 not hno3.

What happens when sulfur trioxide reacts with water?
H2SO4 is formed
What would have happened if sulfuric acid was not add in spectrophotometric titration?
H2SO4 is added in reaction because acidic medium is required and it provides proton to the reaction .
What is the product formed by the reaction ''KBrO3 plus KBr plus H2SO4''?
KBrO3 and KBr do not react with each other because they have same cation K+, but separately they react with H2SO4. 2KBrO3 + H2SO4 -------> K2SO4 + 2HBrO3 2KBr + H2SO4 ----------> K2SO4 + 2HBr
What is the function of sulfuric acid in redox titration?
Sulphuric Acid (H2SO4) is used in the redox titration process because it provides the H(+) ions necessary for the reaction to occur more quickly whilst the sulphate(-) ions barely react during the reaction.
Why you do not use HNO3 or HCL in titration of redox?
HNO3 is not used in redox titration because being a good oxidising ageant it oxidises the compound itself whereas HCL is a very volatile and it takes part in the reaction therefore H2SO4 is used in the reaction
What happens when Iron sulfide is added to hydrochloric acid?
Iron sulphide slowly dissolves in acid giving Hydrogen sulphide gas and a dirty green solution along with a burning sulpher smell. FeS + 2HCl ---------> FeCl2 + H2S
