ELECTROLOYSIS OF WATER: DETERMINATION OF THE FUNDAMENTAL ELECTRONIC CHARGE PURPOSE: The fundamental electronic charge of water will be determined. A system of collecting the formation of H2 and O2 using two inverted glass collections tubes and a 1-L beaker filled with water will be setup. An electrolyte (H2SO4) will be added to water to make it an electrical conductor. A small amount of electricity will be applied to the water (roughly 400 mA) to oxidize the oxygen and reduce the hydrogen

Alana Rogers Date of experiment:11-20-13 Date submitted: 11-23-13 Determination of Water Hardness Using a Titrator Purpose: This purpose of this experiment was to determine the hardness of the local water supply. Be familiar with using a titrator. To tell wether your water is hard or soft. Hard water however does not create a threat‚ but is bad for your pipes causing them to crust. To measure water’s “softness” you are truly measuring the amount of CaCO3 in the water. Procedure: Assemble

Essay Plan Is the goal of national self-determination (according sovereign statehood to each national community) compatible with ideals of global justice? Draw critically upon a theory (or theories) of justice to explain and give reasons for your answer. Introduction • Justice – the core notion of justice to revolve around the idea that some entity is entitled‚ as a matter of right rather than charity‚ to receive the treatment proper to it - BROWN • National self-determination • Cosmopolitan

Determination of the Solubility Product Constant of Calcium Hydroxide Introduction The equilibrium constant for the solubility equilibrium between an ionic solid and its ions is called solubility constant [1] ‚ Ksp of the solute. For example‚ the solubility product is defined by MxAy(s) ⇋xM(aq)y++ yA(aq)x- (1) Where M is the metal cation‚ A is the anion‚ x and y are the corresponding charges of the ions. The equilibrium expression is Ksp=[MY+]x[AX-]Y (2)

Gravimetric determination of sulphate in fertiliser Question: The proportion of sulphate present in a brand of commercial fertiliser under a range of temperatures. Fertilisers provide plants with a number of sources necessary for them to grow‚ as follows‚ nitrogen‚ phosphorus‚ potassium and finally the one I will be concentrating on Sulfur. To cater for the varying plants‚ you wouldn’t require all these elements to the same extent as the necessities for each plant differ. The composition of different
