Calcium hydroxide, Ca(OH)2, is a strong base. A 0.30M solution of calcium hydroxide has a hydroxide ion concentration (to two significant figures) of M.

Calcium oxide is reacted with water to produced calcium hydroxide, a widely used base:CaO(s) + H2O(l) → Ca(OH)2(s)a.     How much calcium hydroxide is produced by the complete reaction of 150.0 g CaO with excess of water?

What is the common name for calcium hydroxide dissolved in water?

Calcium hydroxide and phosphoric acid react to form calcium phosphate and water. Ca(OH)2 +  H3PO4 --> Ca3(PO4)2 + H2OHow many grams of Ca(OH)2 are needed to produce 1,076 grams of Ca3(PO4)2?Write your final answer in two decimal places.Use the following mass numbers:Ca - 40 g/molH - 1 g/molO - 16 g/molP - 31 g/mol

HLDifficulty: Multiple choice questionSodium hydroxide solution reacts with calcium chloride solution according to the following equation:2NaOH(aq) + CaCl2(aq) → 2NaCl(aq) + Ca(OH)2(s)30.0 cm3 of 0.500 mol dm–3 NaOH(aq) reacts with 20.0 cm3 of CaCl2(aq). Calculate the concentration of the CaCl2 solution (in mol dm–3).

Balance the following equations by adding the stoichiometric ratios and ionic charges (include the + or - charge).  Do not leave the boxes blank or it will mark you incorrect.  If the stoichiometry is 1 please insert 1 in the box(es) below.  You don't have to add a 1 for the charge.Calcium hydroxide is dissolved in water Ca(OH)2(s)   →    Ca (aq)   +    OH (aq)
