In terms of grammar, “reduce the acidity of the solution.”
Answer:
3, H⁺ acceptor
Explanation:
Let's consider Bronsted-Lowry acid-base theory.
According to this theory, an acid is a substance that donates H⁺ ions. For example, HCl is an acid.
HCl + H₂O = Cl⁻ + H₃O⁺
Cl⁻ is the conjugate base of HCl.
According to this theory, a base is a substance that accepts H⁺ ions. For example, NH₃ is a base.
NH₃ + H₂O = NH₄⁺ + OH⁻
NH₄⁺ is the conjugate acid of NH₃.
The ksp value for calcium hydroxide at this temperature is 5.20 × 10⁻⁶.
<h3>What is ksp?</h3>
Ksp is an equilibrium constant of a solid substance dissolved in a liquid solution.
Given that, the volume of water is 0.178 l, 0.264 g of Ca(OH)² dissolves in enough water
The solution equilibrium is
Ca(OH)² = Ca + 2OH
The molar solubility is
0.186 / 74.00 / 0.230 = 0.0109 M
The ksp value will be
Ksp = (s) (2S)²
Putting the values in the formula
(0.0109) x (2 x 0.0109)² = 5.20 × 10⁻⁶.
Thus, the ksp value for calcium hydroxide is 5.20 × 10⁻⁶.
