Question

Short answer

Struvite crystallizes in the orthorhombic system as white to yellowish or brownish-white pyramidal crystals or platy mica-like forms. It is a soft mineral with Mosh hardness of 1.5 to 2 and has a low specific gravity of 1.7.

The chemical equation for the dissolution of in water

${\text{MgNH}}_{4}PO.6H_{2}O\left(s\right)\to M{g}^{2+}\left(aq\right)+N{H}_4^{+}\left(aq\right)+P{O}_4^{3-}\left(aq\right)+6H_{2}O\left(l\right)$

Struvite crystallizes in the orthorhombic system as white to yellowish or brownish-white pyramidal crystals or platy mica-like forms. It is a soft mineral with Mosh hardness of 1.5 to 2 and has a low specific gravity of 1.7.

The chemical equation for the dissolution of in water

${\text{MgNH}}_{4}PO.6H_{2}O\left(s\right)\to M{g}^{2+}\left(aq\right)+N{H}_4^{+}\left(aq\right)+P{O}_4^{3-}\left(aq\right)+6H_{2}O\left(l\right)$

Solubility product expression

The solubility product expression is :$K_{sp}=\left[M{g}^{2+}\right]\left[N{H}_4^{+}\right]\left[P{O}_4^{3-}\right]$
