The solubility of many compounds depends strongly on the pH of the solution. For example, the anion in many sparingly soluble salts is the conjugate base of a weak acid that may become protonated in …

Oct 6, 2023 · In summary, the pH affects the solubility of CaF₂ significantly because F⁻ can form HF in the presence of H⁺, whereas Cl⁻ does not have a similar influence due to HCl being a strong acid.

In summary, while CaF2 demonstrates limited solubility in water, environmental factors such as pH and the presence of acids can significantly influence its dissolution behavior.

Deposits of fluorite are formed through a process called hydrothermal precipitation in which calcium and fluoride ions dissolved in groundwater combine to produce insoluble CaF 2 in response to some …

Nov 14, 2018 · Using the information at pH=7, I estimated that $K_ {sp}\approx3.7\cdot10^ {-11}$, which means that barely any HF formed. I assumed that only $HF$ forms and not $CaOH$ because it's …

As a common depressant, acidified water glass (AWG) has strong inhibitory effects on fluorite and calcite. The inhibited fluorite is difficult to be recovered, thus resulting in the waste of...

Sep 5, 2022 · There are three kinds of gases that can make clear lime water cloudy: carbon dioxide, sulfur dioxide, and hydrogen fluoride, summed up The solubility of Calcium Fluoride CaF2 is not …

Nov 15, 2020 · Certainly, adding an acid (H +) that didn't also contain the common ion (F -) would increase the solubility, but I'm under the impression that adding both will not have that same effect.

May 23, 2024 · Therefore, the pH does not affect the solubility of CaF2 in this problem.step 6 When the pH is buffered at 2, the HF solution is moderately acidic and this will affect the concentration of F- …

Why does ph affect the solubility of CaF2 significantly but not that of CaCl2? Why can F form an acid, and why can't Cl form an acid? Aren't both able to form an acid if there's hydrogen/h2o in the …
