The pH of the solution will be lowered. Currently the solution is Neutral (salt water). Adding an acid will turn the solution slightly acidic
Answer: C) the rate of forward reaction is not equal to the rate of backward reaction. This should be the answer.
Explanation:
Answer:
4x^3
Explanation:
Solubility product constant is usually written as (Ksp). It is defined for equilibrium between a solids and its respective ions in a solution. Its value indicates the degree to which a compound dissociates into ions in water. The higher the solubility product constant, the more soluble the compound.
Solubility of a solute is defined as the maximum amount of solute that can be dissolved in a solvent at equilibrium while the solubility product constant (Ksp) describes the equilibrium between a solid and its constituent ions in a solution.
For AB2(s)< -------> A(aq) + 2B(aq). But solubility of AB2= x
Ksp= x × (2x)^2
Ksp= 4x^3
As the pressure on the on a gas cofined above a liquid increases, the solubility of the gas will increase
this also happen when we lower the temperature
Answer:
a) Explain why:
(i) All the elements of a group have similar chemical properties.
(ii) All the elements of a period have different chemical properties.
(b) The atomic radii of three elements X, Y and Z of a period of the periodic table are 186 pm, 104 pm and 143 pm respectively. Giving a reason arrange these elements in the increasing order of atomic number in the period.
