Answer :
(A)
: It is soluble in water.
(B)
: It is insoluble in water.
Explanation :
Solubility : It is defined as the amount of solute dissolved in a solvent at a given temperature.
According to the solubility rules:
All chlorides are soluble except 
All sulfates are soluble except 
From this we conclude that,
(A)
: It is soluble in water.
(B)
: It is insoluble in water.
Answer:
10.96
Explanation:
<em>A solution is prepared at 25 °C that is initially 0.14 M in diethylamine, a weak base with Kb = 1.3 × 10⁻³, and 0.20 M in diethylammonium chloride. Calculate the pH of the solution. Round your answer to 2 decimal places.</em>
Step 1: Calculate the pOH of the solution
Diethylamine is a weak base and diethylammonium (from diethylammonium chloride) its conjugate acid. Thus, they form a buffer system. We can calculate the pOH of this buffer system using the Henderson-Hasselbach's equation.
pOH = pKb + log [acid]/[base]
pOH = -log 1.3 × 10⁻³ + log 0.20 M/0.14 M
pOH = 3.04
Step 2: Calculate the pH of the solution
We will use the following expression.
pH + pOH = 14
pH = 14 - pOH = 14 -3.04 = 10.96
The temperature decreases
