The goal for our lab activity was to make a silver mirror by reducing silver ions with dextrose. The materials that we used were acetone‚ 5 mL of 1.5 M ammonium nitrate solution (NH4NO3)‚ 5 mL of 0.5 silver nitrate solution (AgNO3)‚ 10 mL of 5% dextrose solution (C6H12O6)‚ 10mL of 10% sodium hydroxide solution (NaOH)‚ a 50 mL beaker‚ a 250 mL Florence flask with a rubber stopper‚ a 10 mL graduated cylinder‚ a waste beaker‚ and distilled water. The first thing we did was rinsed the beaker‚ cylinder

EXPERIMENT NO. 5 COMMON ION EFFECT Lopez‚ Pauline G. HIJ-2‚ Group No. 5‚ Ms. Jervee M. Punzalan Ramales‚ Ayane Mark Q. September 15‚ 2014 I. ABSTRACT The common ion effect involves how the solubility of a salt changes when some ion that is common to both added substance and the salt in question is introduced. The presence of a common ion hinders the ionization of a weak acid or a weak base hence this is known as the common ion effect. Simply put‚ the effect

Ecology EQ’s 2. Abiotic and biotic components influence each other. For instance‚ temperature (abiotic factor) can make plants (biotic factor) reproduce more or reproduce less. Also water‚ an abiotic factor‚ has an effect on how animals‚ a biotic factor‚ survive in certain areas of the world. 3. Because a different niche allows multiple species of organisms to coexist. If all organisms had the same niche‚ then there would be heavy competition for food‚ shelter‚ etc. Having different niches gives

System I: Ion Channels 1. What structures in the cell membrane function as ion channels? Integral Proteins 2. Ion channels are selective for specific ions. What three characteristics of the ions are important for this selectivity? 1. Charge 2. Size 3. Amount of water the ion attracts 3. Channels can be classified as either gated or nongated channels. A sodium channel that is always open would be classified as a/an __________nongated______________ channel. 4. Would sodium ions move into

Essential Fatty Acids (EFAs) are fats that are required by the human body‚ but cannot be made by the body; therefore they must be obtained from external forces such as food. EFAs are the building blocks of all fats and oils and are required for both metabolic processes and for fuel. EFAs form the main component in the fats carried in our blood stream (triglycerides)‚ fats stored in our bodies and of cell membranes (phospholipids). (Erasmus‚ 1993)‚ (Wikipedia‚ Essential Fatty Acids‚ 2012) Two fundamental
