Answer: K2S ( Potassium sulfide ) is Soluble in water What is Soluble and Insoluble ? Solubility Solubility is the property of a solid, liquid, or gaseous chemical substance called solute to dissolve in a solid, liquid, or gaseous solvent.
X and Y both form hydroxide compounds, but X(OH) 2 is more soluble in water than Y(OH) 2. BaS, CaS, and MgS are sparingly soluble. Magnesium Sulfide (MgS) is sparingly soluble in water due to the following reasons: Our experts can answer your tough homework and study questions.
Potassium sulfide is the inorganic compound with the formula K 2 S.The colourless solid is rarely encountered, because it reacts readily with water, a reaction that affords potassium hydrosulfide (KSH) and potassium hydroxide (KOH).
Nov 14, 2020 · A soluble compound will dissociate because of the attractions with the surrounding water molecules are strong enough to separate the ions. For an ionic compound to dissociate, the forces of attraction between its component ions and the surrounding water molecules must be greater than the forces of attraction between the ions within the compound.
Solubility in Water: Whether a given salt is soluble in water or not depends upon the ions present in the salt. Salt containing {eq}K^+ {/eq} ions, and {eq}Cl^- {/eq} ions are soluble in water.

Similarly, is copper sulfide soluble in water? Chemical Properties Copper (II) sulfide , CuS, [1317-40-4], MW 95.6, occurs in nature as the blue-black mineral covellite, [19138-68-2]. It is insoluble in water but is decomposed by nitric acid.
The salt is soluble in water, but insoluble in solutions of potassium hydroxide (sp. gr. 1.35), or in absolute ethanol. When potassium sulfate is heated in water and subject to swirling in a beaker, the crystals form a multi-arm spiral structure when allowed to settle.
Cadmium Sulfate is a whitish, crystalline, inorganic compound that forms toxic fumes of cadmium oxides when heated. Calcium sulfate is used in electroplating, vacuum tubes, fluorescent screens, analytical chemistry, as a fungicide and as a chemical intermediate to produce cadmium containing pigments and stabilizers.
When added to water to form an aqueous solution we can see that it dissolves, that is, the lattice of ions is broken up so that each ion is completely surrounded by water, that is, sodium hydroxide completely dissociates in water: NaOH (aq) → Na + (aq) + OH-(aq) Therefore there will be lots of ions in solution to conduct electricity.
