Answer : D
Why ? : Because dissolved minerals would be a liquid and later solidifies into a crystal which would be in phase of being a solid
The pH value of the solution is mathematically given as
pH=2.35
<h3>What
pH value of the
solution?</h3>
Question Parameters:
pH during the titration of 20.00 mL of 0.1000 M dimethylamine,
with 0.1000 M HCl(aq) after 21.23 mL of the acid
Generally, the equation for the Chemical Reaction is mathematically given as
(CH3)2NH(aq), +Hcl ---> <---- (CH3)2NH2Cl(aq)
Therefore
HCL=0.00444M
WHere
HClaq--->H+(aq)+Cl-(aq)
Hence
H+=0.00444M
pH= -log{H+}
pH=log(0.00444)
pH=2.35

Answer:
- <em>The addition of a small amount of HCl to a solution containing fluoride ions and hydrogen fluoride</em> <u>will cause the equilibrium shift to the production of more hydrogen fluoride.</u>
Explanation:
The solution containing <em>fluoride ions and hydrogen fluoride</em> (a weak acid) may be chemically represented by this equilibrium equation:
- F⁻ (aq) + H⁺ (aq) ⇄ HF (aq)
The <em>HCl</em>, a strong acid, added will ionize in water according to this chemical equation:
- HCl (aq) → H⁺ (aq) + Cl⁻ (aq)
Then, following Le Chatelir's principle, the addtion of H⁺ ions coming from the HCl dissociation, will increase the concentration of H⁺ in the solution, driving to the consumption of some F⁻ ions, and the production of more HF acid. This is a shift of the equilbrium toward the HF side.
