    I have a mystery hydroxide. I dissolve 3.70g of it in 1dm^3 of water. I remove 100cm^3 portion and dilute it up to 1dm^3. 25cm^3 portions of the diluted solution are titrated against HCl at a concentration of 0.006mol/dm^3, requiring 41.7cm^3 of acid to fully neutralize it. If 1 mole of Hydroxide (Solid) releases 2 moles of OH- ions, propose and identity for the hydroxide.

    Balanced Equation: X(OH)2 +2HCl = XCl2 +H2O
