Is K2SO4 soluble or insoluble?
Is K2SO4 soluble or insoluble?
K2 SO4 is very soluble in water. Most alkali metal compounds are water soluble and potassium is an alkali metal.

Why is K2SO4 neutral?
Potassium Sulphate(K2SO4) is prepared by combining KOH(potassium Hydroxide) and H2SO4(Sulphuric Acid). As H2SO4 is a strong acid and KOH is a strong base,so K2SO4 is a neutral salt.
Is K2SO4 soluble in water?

Is KBR aqueous or solid?
It is freely soluble in water; it is not soluble in acetonitrile. In a dilute aqueous solution, potassium bromide tastes sweet, at higher concentrations it tastes bitter, and tastes salty when the concentration is even higher….Potassium bromide.

Is PbS soluble in water?
PbS shows a very low solubility in water, and it is insoluble in organic solvents. Any “dissolution” process in acids (hydrochloric acid, nitric acid, aqua regia) is accompanied with a chemical reaction whereby H2S is liberated and the corresponding soluble Pb2+ salts are formed.
What is oxidation state of S in K2SO4?
Hence, oxidation state of S in K2SO4 is +6.
Is K2SO4 strong or weak?
Potassium sulfate (K2SO4) is an extremely strong acidic compound (based on its pKa).
Is an aqueous solution of K2SO4 acidic basic or neutral?
From my knowledge, K+ is an unreactive ion as it produced from the dissolution of the strong base KOH. However, SO42- is produced from the dissociation of weak acid HSO4- so it is slightly basic. So the product K2SO4 would be slightly basic.
What happens when KBr melts?
When potassium bromide, KBr, is dissolved in water it dissociates into potassium ions, K+ and bromine ions, Br- ions. molecules or ions, thus dissolving them.
Is KBr brittle?
As it turns out, KBr is classified as an ionic solid because the electronegativity difference between K and Br is such that ions (K⁺ and Br¯, respectively) are expected to form. brittle, solid that is a poor electric conductor as such; electrically conductive aqueous solutions.
Is PbS a solid or aqueous?
Physical properties: Lead (II) sulfide is a black crystalline solid or a silver powder. Its density is 7.5 g mL-1. Its melting point is 1114 ºC and its boiling point is 1281 ºC. It is insoluble in water and soluble in nitric acid hot and hydrochloric acid.
Is the aqueous solution of K2SO4 acidic or basic?
Is an aqueous solution of K2SO4 (potassium sulfate) acidic or basic? From my knowledge, K+ is an unreactive ion as it produced from the dissolution of the strong base KOH. However, SO42- is produced from the dissociation of weak acid HSO4- so it is slightly basic. So the product K2SO4 would be slightly basic.
Which is an unreactive ion K + or H2SO4?
K+ is an unreactive ion as it is produced from the dissolution of the strong base (KOH). Potassium sulphate (chemical formula K2SO4) is prepared by the action of potassium hydroxide (KOH) and sulphuric acid (H2SO4). 2KOH (aq) + H2SO4→ K2SO4 (aq) + 2H2O (l)
What is the pH of 0.1 m K2SO4?
It is almost neutral, because SO42- is a very weak base (pKb is around 12). According to CurTiPot a 0.1 M solution has a pH of 7.290.
Which is the base of H2SO4 and potassium sulfate?
Potassium sulfate is the salt of a strong acid (H2SO4) and a strong base (KOH) and the pH of its aqueous solution is roughly neutral.
