An instrument used to determine the standard reduction potentials of other elements and complexes. It is made up of a platinum metal rod (which adsorbs and thereby, holds H molecules on its surface) dipped in acidified water. For this hydrogen is assumed to be of Eo = 0. When connected to material whose Eo has to be found out. Then, the Eo is found out by equation Eo (cell) = Eo (cathode) - Eo (anode). Eo (cell) is found experimentally and if hydrogen electrode undergoes oxidation, it is anode and if it undergoes reduction, it is cathode.

Why is the mass determined bu measuring a colligative property in case of some solutes are abnormal ? Disscuss it with the help Van't Hoff law

Anjan Karthi 3 years ago

Some times, the solute molecules, on dissolving in the solution, may undergo association or dissociation resulting in a net change in the quantity of solute particles in the solution. This can affect the value of colligative properties and thereby, the values of molar masses too. This is called ABNORMAL MOLAR MASS.

ANSWER

Why electrophilic substitution in benzoic acid takes place at meta position

Posted by Akansha Rana 3 years, 1 month ago

CBSE > Class 12 > Chemistry

1 answers

Anjan Karthi 3 years ago

During resonance stabilisation, the ortho and para positions of the benzene ring with respect to the carboxy group attains momentary positive charges. Thus, the meta position is RELATIVELY favourable for incoming electrophilic substitutions in benzoic acid.

Ayush Singh 3 years, 1 month ago

Number of atoms in 0.4 mole of compound = 0.4 x 6.022 x 10²³ = 2.4088 x 10²³ Number of octahedral voids = Number of atoms in close packing = 2.4088 x 10²³ Number of terahedral voids = 2 x No. of atoms in close packing = 2 x 2.4088 x 10²³ = 4.8176 x 10²³ Total number of voids = 2.4088 x 10²³ + 4.8176 x 10²³ = 7.2264 x 10²³.
