According to Avogadro’s law, at the same temperature and pressure, an equal volume of gases contains the same number of molecules regardless of the chemical nature and physical properties. Avogadro’s number = 6.023 X 1023

Valency is a property of groups or atoms, equal to the number of atoms of hydrogen that the group or atom could combine with or displace it in forming compounds.

Both techniques are used to the amount of chemical present in the solution.  However, they are almost similar but differs in Molarity Normality Molarity is used to know the total amount of molecules in a 1-liter solution Normality is used…

Mention the formula to calculate pH of a solution? In order to calculate the pH of a solution you have to use the formula pH= -log [H+] or pH = -log [H3O+]

Explain what is the difference between fractionation and distillation? Both methods are used to separate the components present in the solution based on the boiling points.

How will you calculate how many moles of glucose present in 320 mL of 5.0 M of glucose solution? First step: Convert the volume from millilitres to litres Second use the formula = M x V = 5.0 moles glucose/…

Mole is the unit used to define the number of chemical substance present in a substance. It is the amount of substance which consists of the same number of chemical units as there are atoms in exactly 12 gram of…

In buffer when hydrogen ion is added, it will be neutralized by the base in the buffer.  Hydroxide ion will be neutralized by the acid.  On the overall pH of the buffer solution, these neutralization reactions will not show much…

A buffer is an aqueous solution which has highly stable pH. It is a blend of a weak acid and its conjugate base or vice versa. On adding a small amount of base or acid to buffer, its pH hardly…

Titration is a process to determine the molarity of a base or an acid.  In this process, a reaction is carried out between the known volumes of a solution with a known concentration, against the known volume of a solution…
