OCR A-Level Chemistry Flashcards covering the entire specification. I found these flashcards really useful but wanted spaced repition with them as well as not having to pay the extortionate monthly fee (cognito)
Includes: Module 2 - Foundations in Chemistry Module 3 - Periodic Table and Energy Module 4 - Core Organic Chemistry Module 5 - Physical Chemistry and Transition Elements Module 6 - Organic Chemistry and Analysis
| Front | How can you identify the relative molecular mass of a molecule from its mass spectrum? |
| Back | The relative molecular mass of a molecule corresponds to the m/z value of the molecular ion (M) peak, which is typically the peak at the highest m/z value. |
| Front | What suffix is used to name esters? |
| Back | Esters are named using the suffix -oate. |
| Front | Why is potassium iodide (KI) added in iodine-thiosulfate titrations? |
| Back | Potassium iodide reacts with an oxidising agent through a redox reaction to produce iodine (I2) which is then available for the titration reaction. |
