Chapter 4 Reactions in Aqueous Solutions
www1.udel.edu4.1 General Properties of Aqueous Solutions •Solution - a homogeneous mixture –Solute: the component that is dissolved –Solvent: the component that does the dissolving Generally, the component present in the greatest quantity is considered to be the solvent. Aqueous solutions are those in which water is the solvent.

Answers: 3 Ag+(aq) + PO 4 3–(aq) → Ag 3 PO 4 (s) 4. (a) Write a balanced molecular equation for the reaction between aqueous solutions of acetic acid (CH 3 COOH) and barium hydroxide, Ba(OH) 2.
Determination of Ethanol Concentration in Aqueous Solutions
www.canterbury.ac.nzAqueous Solutions Introduction This method uses a redox titration to find the concentration of ethanol in an aqueous solution. The ethanol is oxidised to ethanoic acid by reacting it with an excess of potassium dichromate in acid. 2 Cr 2 O 7 2− + 16 H+ + 3 C 2 H 5 OH → 4 Cr3+ + 11 H 2 O + 3 CH 3 COOH The amount of unreacted dichromate is then

webs.anokaramsey.eduEmergency Overview: A pale yellow aqueous solution with a pungent sulfur-like odor. Non-combustible but excessive heat may liberate sulfur dioxide gas that is strongly irritating to the eyes and mucous membranes. The solution itself is relatively non-toxic and poses little immediate hazard to fire fighting personnel in an emergency situation.
