Liquid Dosage Forms. Solution: . solutions are clear Liquid preparations containing one or more active ingredients dissolved in a suitable vehicle.. . Suspension:. (Solid in Liquid dispersion) Liquid preparations containing one or more active ingredients suspended in a suitable vehicle.. The electrolysis of aqueous solutions. Aqueous. solutions are solutions in . water. .. Water is a very weak electrolyte. It ionises very slightly to give hydrogen ions and hydroxide ions.. H. 2. O. (l). Pg. 658 - 660. Let’s talk about the lab…. In lab the reactions were spontaneous!. The solutions were arranged so that the electrons would move through the wires. Voltaic cells involving spontaneous reactions are typically used to run motors and perform other useful work. Putting electrical energy in to force the . nonspontaneous. change. electrolysis. Opposite process to electrochemical (voltaic) cells. Electrical energy is put into the reaction. The . nonspontaneous. Mr. Chapman. Electrolysis.
