The solubility product for barium sulfate is 1.1 × 10–10. calculate the molar solubility of barium sulfate.
Triss [41]
When it comes to equilibrium reactions in chemistry, there are a lot of equilibrium constants that can be used. In the case of solubility, the appropriate one to use is the equilibrium constant of solubility product denotes as Ksp. This is the concentration of products raised to their coefficients. For example,

 cC ⇔ aA + bB 

Ksp = {[A^a][B^b]}

Now, for the this problem, the reaction is

BaSO₄ ⇔ Ba²⁺ + SO₄²⁻

The reaction is already balanced. Since we don't know the value of Ba²⁺ and SO₄²⁻, let's denote this at x.

1.1 × 10⁻¹⁰ = [x][x] =[x²]
[x] = [Ba²⁺] = [SO₄²⁻] = [BaSO₄] = 1.049 × 10⁻⁵ M

The intensity of a sound describes
baherus [9]
The intensity of a sound describes <em>its loudness at a particular distance</em><em />

Sound intensity is factored by the ear's sensitivity to the particular frequencies contained in a sound

Sound loudness describes the strength of the ear's perception of a sound.

These two points being said, if the ear is more sensitive to a frequency, that sound will be louder to us than sounds at different frequencies that might not be as sensitive to our ears. <em>So, the more intense the sound, the louder it is ;)</em>

Thank you for your question! I hope this helped! Have an amazing day! :D
