Therefore‚ adding pH buffer to amylase will affect the enzyme’s function upon its addition to starch‚ which can be indicated by the iodine test. In fact‚ if the enzyme is denatured by the pH buffer‚ the iodine will turn blue-black when starch and enzyme solutions are added because the enzyme didn’t digest the starch. However‚ if the optimum pH is added 1 " H o w A m y l a s e Wo r k s . " L e s s o n S n i p s . L e s s o n S n i p s ‚ n . d . We b . 1 0 J a n 2 0 1 1 . < h t t p : / / w w w. l e s s

pH indicators‚ in chemistry‚ are usually a weak acid or base that are naturally occurring in various plants and flowers and can act as dyes. Some examples of indicators are Litmus (Comes from a plant species called a lichen)‚ Phenolphthalein‚ Thymol blue‚ Bromocresol green and Universal indicator. All these indicators have a certain turning point in color once a certain concentration equilibrium of Hydrogen cations in reached (H +) or a certain concentration equilibrium of H3O+(Also OH - using Arrhenius

mL beaker reached 80°C and this was determined based on the glass thermometer. This heated solution was then poured immediately into the vacuum filtration system. The vacuum filtration system was set-up and ran identical to the experiment listed above. 10 mL of the 80°C saturated calcium hydroxide solution was measured using a 10 mL graduated cylinder. The 10 mL of the 80°C saturated calcium hydroxide solution was transferred to a 500 mL beaker from the 10 mL graduated cylinder. A stir bar was placed

Introduction The aims of the lab session was to familiarize with the principles‚ operation and application of a light spectrophotometer. This report discusses an experiment to study the relationship of absorbance and concentration‚ the interaction of electromagnetic radiant energy(ERE) and matter which is an important aspect of the Beer-Lambert ’s Law. This law states that the absorption of a compound is directly proportional to the concentration of that particular compound. This is because (a &
