Solubility

Solubility is the property of a solid liquid or gaseous chemical substance called solute to dissolve in a solid liquid or gaseous solvent The solubility of a substance fundamentally depends on the physical and chemical properties of the solute and solvent as well as on temperature pressure and presence of other chemicals (including changes to the pH) of the solution

18 7: Solubility and pH

May 13 2020In contrast pH has little to no effect on the solubility of salts whose anion is the conjugate base of a stronger weak acid or a strong acid respectively (e g chlorides bromides iodides and sulfates) For example the hydroxide salt Mg(OH) 2 is relatively insoluble in water:

Carbonate Solubility

Use of Acid Distributions in Solubility Problems For solutions with controlled pH the counter ion solubility effects are easily accounted for in determining the solubility of a salt producing a conjugate base Say we have a metal/conjugate base salt MA that ionizes (dissociates) in solution by where A n-is a conjugate base of an acid with equilibria

Solubility Products

The solubility product constant of lead(II) sulfide is much smaller than that of zinc sulfide so it is the least soluble sulfide When a solution that is 0 10 M in each metal ion and 0 30 M in hydronium ion is saturated with hydrogen sulfide lead(II) sulfide precipitates but zinc ion remains in solution

Thus we find that at pH = 8 virtually no Zn(OH)4-2 (instability constant 2 8~1015 (ref 2)) is present but that Zn(OH)2 (solubility product 4 5~1O-l~(ref 2)) remains undissolved Hence at pH = 8 it will not neutralize any acid But it will do so before the second endpoint (pH-4) is reached Similar calculations are based on the solubility

Solubility

Solubility is the property of a solid liquid or gaseous chemical substance called solute to dissolve in a solid liquid or gaseous solvent to form a homogeneous solution of the solute in the solvent The solubility of a substance fundamentally depends on the used solvent as well as on temperature and pressure The extent of the solubility of a substance in a specific solvent is measured as

How does pH affect solubility? + Example

Jul 19 2014Decreasing the pH increases the solubility of sparingly soluble bases and basic salts Increasing the pH has the opposite effect Many sparingly soluble compounds have solubilities that depend on pH It all involves the application of Le Chtelier's Principle Here are two common examples Bases Zn(OH)_2 is a sparingly soluble base Zn(OH)_2(s) ⇌ Zn^2+(aq) + 2OH^-(aq) If

Corrosion tables — Materials Technology

The corrosion data in this section is mainly based on the results of general corrosion laboratory tests which are not strictly comparable with actual service conditions The corrosion tables provide an initial guide to the selection of materials and are intended to facilitate understanding of the different types of corrosion damage that can arise due to poor material selection
