The chemical equation is given below. Mg3(PO4)2 + 6H2O → 2H3PO4 + 3Mg (OH)2. Magnesium Phosphate reacts with hydrochloric acid forms phosphoric acid and magnesium chloride. Mg3(PO4)2 + 6HCl → 3MgCl2 + 2H3PO4. Uses of Magnesium Phosphate – Mg 3 (PO 4) 2. Used as a source for both magnesium and phosphorus. It is used in the minimal supplements.
If the ion ends in -ate and is added with an acid, the acid name will have an -ic ending. Examples: nitrate ion (NO 3 - ) + H + (denoting formation of acid) = nitr ic acid (HNO 3 ) If the ion ends in -ite and
Define ionic and molecular (covalent) compounds. Predict the type of compound formed from elements based on their location within the periodic table. Determine formulas for simple ionic compounds. In ordinary chemical reactions, the nucleus of each atom (and thus the identity of the element) remains unchanged.
The \(Cr^{3+}\) ion is a relatively highly charged metal cation that should behave similarly to the \(Al^{3+}\) ion and form the [Cr(H2O)6]3+ complex, which will behave as a weak acid: \[ Cr(H_2O)_6]^{3+}_{(aq)} \ce{ <=>>} Cr(H_2O)_5(OH)]^{2+}_{(aq)} + H^+_({aq)}\]
The symbol for the ion is Mg 2+, and it is called a magnesium ion. Nitrogen’s position in the periodic table reveals that it is a nonmetal. Nonmetals form negative ions (anions). A nitrogen atom must gain three electrons to have the same number of electrons as an atom of the following noble gas, neon.
Naming salts and basic ionic compounds follows standard ionic nomenclature rules. In naming acids from binary compounds, the prefix ‘hydro-‘ is used to represent the cation H+, and the suffix ‘-ic’ acid is used to indicate that it is an acidic form. If an acid contains a polyatomic ion, no leading prefix is used to indicate the H+ cation.
Metals form positive ions (cations). A magnesium atom must lose two electrons to have the same number electrons as an atom of the previous noble gas, neon. Thus, a magnesium atom will form a cation with two fewer electrons than protons and a charge of 2+. The symbol for the ion is Mg 2+, and it is called a magnesium ion.
