Similarly, Kb is the base dissociation constant, while pKb is the -log of the constant. The acid and base dissociation constants are usually expressed in terms of moles per liter (mol/L). Acids and bases dissociate according to general equations: HA + H2O ⇆ A- + H3O.

What is pKb in chemistry?

pKb is the criterion used to estimate the alkalinity of the molecule. It is u...

Therefore, the answer is option (A). That is, the molarity of 0.1 N oxalic acid is 0.05 M.

What does 0.1 N NaOH mean?

So the equivalent weight of NaOH is 40. To make 1 N solution, dissolve 40.00 g of sodium hydroxide in water to make volume 1 liter. For a 0.1 N solution (used for wine analysis) 4.00 g of NaOH per liter is needed.

Which has normality of 0.1 N?

No...

Standardization is the process of determining the exact concentration (molarity) of a solution. Titration is one type of analytical procedure often used in standardization. In a titration, an exact volume of one substance is reacted with a known amount of another substance.

What is considered a standard solution?

A standard solution is a a solution of accurately known ...

Its chemical formula, C8H18, reflects the fact that each of the carbons is covalently bonded to one or two of the other carbon atoms and two to three hydrogen atoms.

What is oil organic chemistry?

It is a complex mixture of hydrocarbons . The carbon atoms are joined together in chains and rings. Crude oil is an important source of fuels such as petrol, kerosene, heavy ...

A graduated pipette is a pipette with its volume, in increments, marked along the tube. It is used to accurately measure and transfer a volume of liquid from one container to another. It is made from plastic or glass tubes and has a tapered tip.

Why is a graduated pipette used in titration?
