has several medical conditions. Dehydration is the more frequently occurring problem. 3. When pH is low‚ hydrogen ion levels in the blood are high and also in the interstitial and peritubular fluid. Hydrogen ion competes with potassium ion for the sodium countercurrent exchanger in the tubules. As hydrogen ion secretion rises (which compensates for the

lattice is collapses and the solid is converted into liquid. The trend in structure is from the metallic oxides containing giant structures of ions on the left of the period via a giant covalent oxide in the middle to molecular oxides on the right. Sodium peroxide‚ magnesium oxide and aluminum oxide are metallic oxide which have high melting and boiling point compared to other period 3 oxide. This is due to their giant ionic structure and the strong ionic bond. Strong ionic bond in the molecule need

measured as the equivalent concentration of calcium carbonate (in milligrams per litre). Water hardness is usually noticed because of difficulty in lathering soap and the formation of a scum in the bathtub. Ca2+ and Mg2+ form insoluble salts with soaps causing precipitation of the soap scum. Another effect of hard water is “boiler scale”. When hard water comes into contact with dissolved carbonates‚ a precipitate of insoluble calcium carbonate forms. This “scale” can build up on the inside of water

process. LITERATURE: The acids in the vinegar make the shell deteriorate. Eggs contain "calcium carbonate"(this is what makes it hard)‚ and vinegar is an acid. When they both combine a chemical reaction takes place‚ and carbon dioxide is released. This is what bubbles are made of. The vinegar makes the egg soft because it takes all the carbon out. Since the egg shell is made out of "calcium carbonate" and is "eaten" up by the acidic vinegar. It leaves behind the inner membrane and gives it the rubbery

Experiment 8 Chemical Kinetics Abstract This experiment was done to determine the effects of the nature of the reactants‚ concentration‚ temperature‚ surface area and catalyst on the rate of chemical reactions. The nature of the reactants implies a difference if the reactants are aqueous or organic‚ acidic or basic or if they occur in the same phase or not. Acid-base reactions‚ formation of salts‚ and exchange of ions are fast reactions while reactions in which large molecules are formed
