ACTIVITY SERIES The activity series of metals is an list of metals ranked in order of decreasing reactivity to displace hydrogen gas from water and acid solutions. It can also be used to predict which metals will displace other metals in aqueous solutions. In introductory chemistry‚ the reactivity series or activity series is an empirical series of metals‚ in order of "reactivity" from highest to lowest. It is used to summarize information about the reactions of metals with acids and water‚ single

Practical: The effect of pH on enzyme activity Rationale Amylase is an enzyme involved in the digestion system which catalyses the breakdown of starch into sugars. It is not only present in human saliva but also in the pancreas‚ where it hydrolyses dietary starch into disaccharides and trisaccharides which are converted by other enzymes to glucose to supply the body with energy. pH has an effect on the activity of all enzymes‚ including amylase. As the pH level increases‚ the enzyme activity increases
