Why does BaSO4 not dissolve in water?
Why does BaSO4 not dissolve in water?
The ionic compounds BaSO4 is insoluble in water due to high lattice energy and low hydration energy. Lower the lattice energy and higher the hydration energy more is the solubility.
What is the charge of BaSO4?
+2
How do you identify a precipitate in a reaction?
Precipitation reactions occur when cations and anions in aqueous solution combine to form an insoluble ionic solid called a precipitate. Whether or not such a reaction occurs can be determined by using the solubility rules for common ionic solids.
How do you predict a precipitate?
If there is a precipitation reaction, write the complete and net ionic equation that describes the reaction.
- Solution:
- Step 1: Determine the possible products using the general double displacement equation.
- Step 2: Predict whether either of the possible products is water insoluble.
- Step 3: Write the complete equation.
What is the rule for predicting solubility?
Depending on the solubility of a solute, there are three possible results: 1) if the solution has less solute than the maximum amount that it is able to dissolve (its solubility), it is a dilute solution; 2) if the amount of solute is exactly the same amount as its solubility, it is saturated; 3) if there is more …
What is the solubility table used to predict?
The solubility table on pages 61–62 in the Chemistry 0861 Lab Manual can be used to predict whether or not a given ionic compound is soluble.
Is MgS soluble in water?
The sulfides of all metals except barium, calcium, magnesium, sodium, potassium, and ammonium are insoluble in water. BaS, CaS, and MgS are sparingly soluble.
What is the kb value of BA Oh 2?
Kb=5.0 X 10^-3.
What is the pOH of 2.55 BA Oh 2?
Thus, the pOH of the solution is – 0.71, and it is basic.
What is the h3o +] in a 0.050 M solution of Ba Oh 2?
Answer is: concentration of hydronium ions are 10⁻¹³ M.
