Is K2S a acid or base?
K2SO4 + 4 C → K2S + 4 CO. In the laboratory, pure K2S may be prepared by the reaction of potassium and sulfur in anhydrous ammonia. Sulfide is highly basic, consequently K2S completely and irreversibly hydrolyzes in water according to the following equation: K2S + H2O → KOH + KSH.
What is the pH of K2S?
pH of aqueous K_(2)S solution is K1andK2 for H2S are 1.00×10-7and1.30×10-13 respectively at 25∘C.
What type of salt is K2S?

What type of electrolyte is K2S?
ion. 3.2 K2S is an electrolyte because it is an ionic compound, and ionic compounds conduct electricity when they are molten or dissolved in water.
Is K2S ionic?
The names of ionic compounds composed of the above ions are especially simple. The name of the compound is simply the name of the cation followed by the name of the anion, . e.g, K2S is potassium sulfide.
Is K2S soluble or insoluble?
Potassium Sulfide is a moderately water and acid soluble Potassium source for uses compatible with sulfates.
Is KClO4 an acid or base?
(b) Potassium perchlorate, KClO4, is a neutral salt. Neither K+ nor ClO4- has any tendency to donate or accept a proton in dilute aqueous solutions. The reaction between a strong base KOH and the strong acid HClO4 produces KClO4. (c) Potassium hydrogen sulfate (also called potassium bisulfate) is an acidic salt.
Is CH3NH3Br an acid or base?
(a) Methyl ammonium bromide, CH3NH3Br dissolves in water to form a weakly acidic solution. Ka(CH3NH3 +) is 2.28 x 10-11.
