Document Summary
Chy chapter 4 reactions in aqueous solutions. Concentration how much solute is dissolved in the solution (mol/l) Moles per litre or l-1 or m. In metric: mol dm-3 (1l = 1dm3) molarity= moles of solute volumeof solution (l) Example question: a 250ml sample of solution contains 0. 134 moles of solute. Calculate the molarity of the solution. (remember to convert to litres) Example question: what mass of agno3 is needed to prepare 1. 00l of a 0. 150. When an ionic substance is placed in water, it dissociates into its respective ions. When an ionic compound dissolves, the relative [ ] of the ions introduced. Ba(oh)2 ba2+ + 2oh- and into the solution depend on the chemical formula of the compound. Example question: describe how you would prepare 500ml of. Example question: a solution is prepared by mixing 50. 0ml of. What are the concentrations of ca2+, na+, and no3. (find moles of each find [ ])
