acids and alkalies in these solutions are shielded from attack by other ions.
they have fixed value of pH
these give unionised acid or base on reaction with added acid or alkali.
they have large excess of H+ or OH-ions
Equilibrium constant for a reaction with negative pH value decreases as the temperature increases.
In equilibrium mixture of ice and water kept in perfectly insulated flask mass of ice and water does not change with time.
The intensity of red colour increases when oxalic acid is added to a solution containing iron (III) nitrate and potassium thiocyanate.
On addition of catalyst the equilibrium constant value is not affected.
All measurable properties of the system remain constant.
The opposing processes occur at the same rate and there is dynamic but stable condition.
Equilibrium is possible only in a closed system at a given temperature.
All the physical processes stop at eqilibrium.
Dilute solution of boric acid and hydrogen peroxide are strong anti-septics.
A 0.2% solution of phenol is an antiseptic while 1% solution acts as a disinfectant.
Chlorine and Iodine are used as strong disinfectants.
Disinfectants harm the living tissues.
They retain metallic conductivity.
They are much harder than the pure metal.
They are chemically reactive.
They have melting points than the pure metal.
It is easy to refer multiple recipents at same time,simply add ","(comma) next to the email id. Exfirstname.lastname@example.org,email@example.com
