How many grams of Ca(OH)2 to form 5.0 L of 0.10 M hydroxide solution?
If 42.4 mL of 0.212 M HCl solution is needed to neutralize a solution of Ca(OH)2, how many grams of Ca(OH)2 must be in the solution? Express the mass in grams to three significant digits.
For the reaction 2HCl+Ca(OH)2⟶CaCl2+2H2O how many grams of calcium hydroxide, Ca(OH)2, are needed to react completely with 31.9 g of hydrochloric acid, HCl?
Explanation please. How many molecules are there in a 2.20 grams sample of calcium hydroxide Ca(OH)2?
3. Consider a 0.586 M aqueous solution of barium hydroxide, Ba(OH)2 (aq). How many grams of Ba(OH)2 are dissolved in 0.191 dl of 0.586 M Ba(OH)2 (aq)?
Phenolphthalein turns pink in solutions that are roughly 1.0x10-5 M in hydroxide ions. The only source of hydroxide ions is your Ca(OH)2. Let's assume that the amount of water left behind in the beaker to test for complete transfer is about three drops or 0.15 mL. How many moles of Ca(OH)2 would be present in those three drops if the solution barely turned pink? How many grams of Ca(OH)2?
Calcium hydroxide + hydrogen chloride ------ rightarrow calcium chloride + water Ca(OH)_2 + 2 HCl rightarrow Cacl_2 + 2 H_2O How many grams of calcium chloride will be produced from 4.50 mL of a 0.166M hydrogen chloride solution? (M = moles/L)
