Answer:
0.0099M = [F⁻]
Explanation:
<em>For BaF2, Ksp = 1.7x10⁻⁶</em>
<em />
When BaF₂ is in solution, the equilibrium between the solid and the dissociated ions occurs as follows:
BaF₂(s) ⇄ Ba²⁺(aq) + 2F⁻(aq)
Where Ksp = 1.7x10⁻⁶ is defined as:
1.7x10⁻⁶ = [Ba²⁺] [F⁻]²
<em>Where [] are equilibrium concentrations of each ion in solution.</em>
<em />
That means you will add F⁻ until its concentration exceeds:
1.7x10⁻⁶ = [0.0173] [F⁻]²
9.827x10⁻⁵ = [F⁻]²
<h3>0.0099M = [F⁻]</h3><h3 />
When more F⁻ is added, BaF₂ begins its precipitation.
Answer:
a positive and a negative ion
Explanation:
When an acid dissolves in water, it produces positive hydrogen [H⁺] or hydronium [H₃O⁺] ions.
When a base dissolves in water, it produces negative hydroxide [OH⁻] ions.
Hope this helps.
