strong acid and strong base‚ so‚ theoretically‚ the pH value of the the mixture of these two solution at the equivalence point in the titration process should be seven‚ which means neutral. The second groups is the titration between ammonia and hydrochloric acid. The pH at the equivalence point should be below seven to indicate that the mixture at that point is acid‚ since hydrochloric acid is a strong acid and ammonia is weak base. After find out the pH of the equivalence point‚ find out the corresponding

Arterial Blood Gas Interpretation (ABG) Arterial Blood Gas Analysis is used to measure the partial pressures of oxygen (PaO2)‚ carbon dioxide (PaCO2)‚ and the pH of an arterial blood sample. Oxygen content (O2CT)‚ oxygen saturation (SaO2)‚ and bicarbonate (HCO3-) values are also measured. A blood sample for ABG analysis may be drawn by percutaneous arterial puncture from an arterial line. The ABG analysis is mainly used to evaluate gas exchange in the lungs. It is also used to assess integrity of

optimal ranges under which the enzyme activity is maximized. Also to determine whether saline and alcohol are inhibitors or activators Hypothesis: PH factor prediction: I predict that as the pH increases so the activity of the enzyme will increase until it reaches optimum pH range (pH 7) because the enzyme is less denatured when it reaches the preferred pH level‚ and after this it will decrease because the active site will change in shape and it will no longer accept substrates.

Chapter I Introduction A.) Background of the Study: The Acids‚ bases and salts in the pH range are among the most important chemical compounds used by chemists. For instance‚ hydrochloric‚ phosphoric and citric are acids used to make mineral stain removers‚ toilet bowl cleaners‚ metal cleaners and rust removers. A variety of maintenance chemicals contain these compounds. Alkali maintenance chemicals like degreasers‚ oven cleaners and drain openers contain bases such as Sodium Hydroxide (NaOH)

Reetika Kashyap September 20th‚ 2012 Enzyme Lab What is an enzyme? Enzymes are specialized protein molecules simplifying most of the body’s metabolic processes such as‚ supplying energy‚ digesting foods‚ purifying your blood‚ executing the body of waste products etc. Enzymes act as catalyst by speeding up the reactions that happen in our bodies and decreasing the amount of activation energy needed to break a complex down. A reactant is any given enzymatic reaction is called a substrate for that
