In Grade 11 Chemistry, students have successfully navigated the complexities of chemical bonding, including ionic and covalent bonds, Lewis structures, and molecular shapes. Next week, the focus shifts to metallic bonding and giant covalent structures, followed by an exploration of intermolecular forces to understand how molecular interactions dictate physical properties.
In Grade 12 HL, the class has thoroughly mastered acid-base equilibria, specifically calculations involving pH, pOH, and dissociation constants, as well as the nuances of salt hydrolysis and titration curves. With buffer systems now introduced, the unit will wrap up this Sunday, allowing the class to move into the final unit on electrochemistry. The priority remains completing the syllabus before the start of Ramadan to ensure a smooth transition into dedicated revision.
