The Ksp of AgOH will be 1.98×10⁻⁸
According to the question,
The chemical reaction is:
AgOH (aq) + HCl (aq) ---> AgCl (s) + H₂O (aq)
Now, acc. to the formula:
C₁V₁ = C₂V₂
(AgOH) (HCl)
By substituting the values, we get:
C₁ x 250 ml = 0.0136 x 2.60 ml
C₁ = 0.000141
Now:
AgOH → Ag⁺(s) + OH⁻(s)
Hence,
Ksp will be:
= s²
= (0.000141)²
= 1.98x10⁻⁸
<h3><u>The value of Ksp(Solubility product constant)</u></h3>
When a chemical substance in the solid form is in chemical equilibrium with a solution of that molecule, a solubility equilibrium is a sort of dynamic equilibrium that develops. The solid may dissolve chemically reacting with another component of the solution, such as acid or alkali, or dissolving unaltered.

Answer:
5 cm³.
Explanation:
The following data were obtained from the question:
Volume of water = 35 mL
Volume of water + Rock = 40 mL
Volume of rock =.?
The volume of the rock can be obtained as follow:
Volume of rock = (Volume of water + Rock) – (Volume of water)
Volume of rock = 40 – 35
Volume of rock = 5 mL
Finally, we shall convert 5 mL to cm³. This can be obtained as illustrated below:
1 mL = 1 cm³
Therefore,
5 mL = 5 cm³
Thus, the volume of the rock is 5 cm³.
The moles of magnesium in 1.25 x 1023 are 20.8 mol.
When the system turns pink, then the end point has been attained.
<h3>What is the end point?</h3>
The end point or the equivalence point is the time when the reactants have undergone transformation in accordance with the reaction equation. The reaction in this case is; HCl + NaOH -----> NaCl + H2O.
We know that phenolphthalein is colorless in acid but red in a base. The color at end point is pink. Thus, when the system turns pink, then the end point has been attained.
