In this video we'll balance the equation Ca(OH)2 + H3PO4 = Ca3(PO4)2 + H2O and provide the correct coefficients for each compound.

To balance Ca(OH)2 + H3PO4 = Ca3(PO4)2 + H2O you'll need to be sure to count all of atoms on each side of the chemical equation.

Once you know how many of each type of atom you can only change the coefficients (the numbers in front of atoms or compounds) to balance the equation.

Important tips for balancing chemical equations:

Only change the numbers in front of compounds (the coefficients).
Never change the numbers after atoms (the subscripts).
The number of each atom on both sides of the equation must be the same for the equation to be balanced.

O hidróxido de cálcio, também conhecido como cal hidratada, cal apagada, leite de cal, hidróxido de cálcio em suspensão, neutralac, slake ou ainda cal extinta, é um composto químico de fórmula ca ( oh) 2. Which of the following is the correctly balanced equation for the complete neutralization of h 3po 4 with ca(oh)2 ? 2h3po4 + 3ca(oh)2 → ca3(po4)2 + 6h20 3h3po4 + ca(oh)2 → ca3(po4)2 +5h20 h3po4 + ca(oh)2 → ca3(po4)2 + h20 4h3po4 +6ca(oh)2 → 2ca3(po4)2 + 12h20 0 h3po4 + ca(oh)2 →. H3po4+ca (oh)2 ⇒ ca3 (po4)2+h2o. 2h3po4+3ca (oh)2 ⇒ 1ca3 (po4)2+6h2o. Nossa ta td certo, mt obg serio. Vc pode me chamar de burra mas, eu fiquei hrs tentando achar a resposta. (ta hrs eh um pouquinho mt, mas c entendeu) report flag outlined. In this reaction, phosphoric acid, h_3po_4, a weak acid, will react with calcium hydroxide, ca(oh)_2, a strong base, to produce calcium phosphate, ca_3(po_4)_2, an insoluble salt, and water. Since you're dealing with the reaction between a weak acid and a strong base, you can say that this is a neutralization reaction.
