    different ions. QUESTION If copper (II) sulfate when mixed with sodium carbonate at different quantities combine to form ions in definite ratios. HYPOTHESIS / PREDICTION I believe that the ions will combine in definite ratios due to the fact that the valance electrons will not be changing throughout any chemicals; consequently the ions must combine in definite ratios. EXPERIMENTAL DESIGN A technique is performed in which copper (II) sulfate and sodium carbonate are placed together in various

    must regulate is water; water is everywhere in our body and its balance is essential for proper body function. A very carefully regulated process is solute concentration. If there is a sudden increase in water which enters the extracellular fluid‚ sodium ions will then contribute less to the extracellular solute concentration as the ratio between water and solute has now changed. Osmolality is the amount of solute in a kilogram‚ hence the osmolality in the extracellular space has also decreased.

    They are very reactive metals and do not occur freely in nature. Alkali metals are malleable‚ ductile‚ and are good conductors of heat and electricity. Alkali metals can also explode if they are exposed to water. The Alkali metals are: lithium‚ sodium‚ potassium‚ rubidium‚ cesium‚ and francium. Lithium The mineral petalite‚ which contains lithium‚ was discovered by a Brazilian scientist named Jose Bonifacio towards the end of the 18th century. Then in 1817‚ lithium was discovered by Johan August

    difference in charge is continued by three factors. Firstly‚ in the cell membrane‚ there are sodium potassium ‘pumps’ crossing the membrane which are proteins that bring 2 potassium ions into the cell‚ for every 3 sodium ions it pumps out. As well as this‚ there are protein channels which allow potassium ions in the cell to flow out via facilitated diffusion. Potassium diffuses out the cell much more readily than sodium diffuses in. Lastly there are many negatively charged organic anions such as some amino
