Ammonia (NH3) is an example of a Brønsted-Lowry Base. i. Define the Brønsted-Lowry acid-base theory.
ii. What’s the pH of a solution of ammonia that has a concentration of 0.335 M? The Kb of ammonia is
1.8 × 10–5.

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l
