What is the n-factor of H2SO4 in a reaction where it replaces one H+ ion?

The n-factor of H2SO4 in this reaction is 1.

Fill in the blank: The n-factor of H3PO4 can be ___, ___, or ___.

1, 2, or 3

True or False: The n-factor is the same as the basicity of an acid.

False. The n-factor is not equal to its basicity; it refers to the number of H+ ions replaced by 1 mole of acid.

What is the n-factor of KMnO4 when it acts as an oxidizing agent and its oxidation state changes from +7 to +2?

The n-factor of KMnO4 in this reaction is 5.

Riddle: I can change oxidation states, both up and down, sometimes I am reduced, sometimes I wear a crown. What am I?

A transition metal compound.

Fill in the blank: The n-factor of NaOH is ___ because it replaces one OH- ion.

1

What is the n-factor of a salt that exchanges a total of 6 moles of cationic charge in a reaction?

The n-factor is 3, as each mole of the salt replaces 3 moles of cationic charge.

True or False: In a disproportionation reaction, the same element is both oxidized and reduced.

True.

What does the n-factor represent in the context of salts that undergo change in oxidation state?

The n-factor represents the total moles of electrons exchanged (lost or gained) by one mole of the salt.

Fill in the blank: The n-factor of H3BO3 is ___ because it provides only one H+ ion in solution.
