Oh Toomtles 32: - YouTube Limewater will dissociate like the following equation: ca (oh) 2rightleftharpoonsca^ (2 ) 2oh^ ( ) so, one mole of limewater will contain two moles of hydroxide ions. "6.3072 g" >>"molarity" = "moles of solute"/"volume of solution (in litres)" "0.45 m" = "n"/"0.4 l" "n = 0.45 m × 0.4 l = 0.18 mol" you need "0.18 mol" of "nh" 4"oh" molar mass of "nh" 4"oh" is "35.04 g/mol" mass of solute = 0.18 cancel"mol" × "35.04 g"/cancel"mol" = "6.3072 g".

Hcoo^( )(aq) h 2o(l) rightleftharpoons hcooh(aq) oh^( )(aq) if the solution is diluted, the reaction will shift left, because (i) water isn't in the equilibrium expression, and (ii) each product is in aqueous solution. if naoh is added, then we have increased the concentration of hydroxide ions. the reaction will shift left to re equilibrate and consume the excess oh^ . pressure will have. Six come from two ammonia molecules, meaning that 10 6=4 must come from water molecules. each water molecule contains two hydrogens, so we multiply water by two to get: (nh 4) 2so 4 ca (oh) 2 >caso 4 color (blue)2nh 3 color (red)2h 2o final step is to balance the oxygen. Barium hydroxide is a dibase, the which has no or marginal solubility in water .a concentration of #0.200*mol*l^ 1# is unreasonable .had the question proposed a back titration .i.e. addition of excess nitric acid, the which was back titrated by standardized sodium hydroxide, the question would be kosher.
