WebA gain of electrons or a decrease in oxidation number. A reagent that reduces (adds electrons to) another species. A reagent that oxidises (takes electrons from) another species. The energy required to remove one electron from each atom in one mole of gaseous atoms to form one mole of gaseous 1+ ions. WebWorked example: Identify the functional groups in the molecule C6H12O2, using the infrared spectrum given below. (2 marks) Infrared (IR) Spectroscopy. Answer: Signal at 3230-3350 shows an O-H (alcohol) (1) and C=O at 1680-1750 (1) There are separate -OH and C=O bonds in the molecule, so it is not a carboxylic acid.
WebOCR A-level Chemistry is a qualification in the UK designed for students aged 16 to 18. It is a two-year course that covers a wide range of topics, including organic, physical and inorganic chemistry. The course aims to develop students' understanding of fundamental chemical concepts, as well as their practical skills, analytical and problem ... WebSince the Ag + / Ag half-cell has a more positive Eꝋ value, this is the positive pole and the H + /H 2 half-cell is the negative pole. The standard cell potential (Ecellꝋ) is Ecellꝋ = (+ 0.80) - (0.00) = + 0.80 V. The Ag + ions are more likely to get reduced than the H + ions as it has a greater Eꝋ value.
