Manganese(II) sulfate

Manganese(II) sulfate is an inorganic salt with formula MnSO₄, composed of manganese(II) ions and sulfate ions. It occurs in anhydrous and hydrated forms.

Manganese: Manganese is a chemical element with atomic number 25, known for multiple oxidation states and use in steelmaking. Manganese(II) sulfate supplies manganese in the +2 oxidation state.
Solubility: Solubility is the maximum amount of a substance that dissolves in a specified solvent under stated conditions. Its temperature-dependent solubility governs how manganese(II) sulfate crystallizes from water.
Micronutrient fertilizer: A micronutrient fertilizer supplies essential trace elements that plants need in small quantities. Manganese(II) sulfate supplies soluble manganese to crops with manganese deficiency.
Manganese toxicity: Manganese toxicity is harm caused by excessive manganese exposure, especially through prolonged inhalation or high doses. Excessive exposure to manganese compounds can affect the nervous system.
Sulfate: Sulfate is the polyatomic anion SO₄²⁻, formed from one sulfur atom and four oxygen atoms. Sulfate is the negatively charged ion paired with Mn²⁺ in the salt.
Dissolution: Dissolution is the process by which particles of a solute disperse in a solvent to form a solution. Dissolving the salt separates its ions and surrounds them with water molecules.
Manganese deficiency in plants: Manganese deficiency in plants is a nutrient disorder that disrupts photosynthesis and causes characteristic leaf symptoms. Soil or foliar applications of the salt can correct this deficiency.
Manganism: Manganism is a neurological disorder associated with chronic exposure to high levels of manganese. It illustrates the serious risks of sustained occupational exposure to manganese-containing dusts.
Ionic compound: An ionic compound is a substance whose constituent ions are held together by electrostatic attraction. The formula expresses a charge-balanced pairing of manganese and sulfate ions.
Hydration energy: Hydration energy is the energy change when gaseous ions become surrounded by water molecules. Ion hydration helps explain the salt’s dissolution and the stability of hydrated crystals.
