“A Titration Competition” – Lab #8 1. Since all solutions and aqueous solutions have their own pH‚ it is important for all glassware to be clean and dry before performing a titration. Even a slight trace of a different solution could alter the pH and give an inaccurate titration reading. If the glassware is not completely dry after rinsing‚ the small traces of water could make the solution more dilute than it should be thus changing its concentration. 2. Air bubbles in the burette tip is a

Solutions Solutions are a combination of solvents and solutes. When a solute dissolves into a solvent‚ the combined product of the two reactants is called a solution. The definition of a solute is the reactant that’s being dissolved. The only difference from a solute and a solvent is that the solvent is the one that’s doing the dissolving. Molecules randomly flow in all directions until there is an equal concentration throughout the solution. The dissolving process can vary depending
