Sodium Triuranate, Na₂U₃O₁₀

Sodium Triuranate, Na₂U₃O₁₀, is formed by heating together uranyl sulphate and sodium chloride, and washing the residue with water (see potassium hexa-uranate). It yields lustrous, golden-yellow, rhombic crystals, of density 6.9, insoluble in water, but soluble in dilute acids.
