The simplest way to check whether a system is colloidal is by
electrodialysis
finding out particle size
Tyndall effect
Brownian movement
An example for a strong electrolyte is
urea
ammonium hydroxide
sugar
sodium acetate
D.
sodium acetate
An example for a strong electrolyte is of sodium acetate.
Sodium chloride is an ionic compound where as hydrogen chloride gas is mainly covalent because
electronegativity difference in the case of hydrogen is less than 2.1
hydrogen chloride is a gas
hydrogen is a non-metal
sodium is reactive
An example for a double salt is
potassium ferricyanide
cobalt hexamine chloride
cuprous sulphate
Mohr's salt
The set of compounds in which the reactivity of halogen atom in the ascending order is
vinyl chloride, chloroethane, chlorobenzene
vinyl chloride, chlorobenzene, chloroethane
chloroethane, chlorobenzene, vinyl chloride
chlorobenzene, vinyl chloride, chloroethane
In the case of auto catalysis
product catalysis
solvent catalysis
reactant catalysis
heat produced in the reaction catalysis
Order of reaction is decided by
molecularity
pressure
temperature
mechanism of reaction as well as relative concentration of reactants
Half-life of a reaction is found to be inversely proportional to the cube of initial concentration. The order of reaction is
5
2
4
3
Which among the following statements is false?
The adsorption may be monolayered or multilayered
Particle size of adsorbent will not affect the amount of adsorption
Increase of pressure increases amount of adsorption
Increase of temperature may decrease the amount of adsorption
