Similarly, strong bases like Calcium Hydroxide (Ca (OH)2), Lithium Hydroxide (LiOH), Potassium Hydroxide (KOH) and Sodium Hydroxide (NaOH) fully dissociate in an aqueous solution to give hydroxyl ions. The Brönsted-Lowry theory gave a more comprehensive definition of acids and bases, stating...
For example, suppose 4.0 g of NaOH, or 0.10 mol of NaOH, are dissolved to make 100.0 mL of aqueous solution, while 3.65 g of HCl, or 0.10 mol of HCl, are dissolved to make another 100.0 mL of aqueous solution. The two solutions are mixed in an insulated calorimeter, a thermometer ...
