Web26 nov. 2024 · Many students are unsure how to relate the IB chemistry topics to a real-world situation or problem that they can investigate. To help with this, I’ve produced a list of chemistry IA ideas, together with some example Research Questions (RQ). I’ve grouped them together according to the main experimental technique or measurement method. http://www.chemistrylabmanual.com/uploads/2/5/6/1/25614215/kinetics.pdf

Experiment 22 IODINE CLOCK - THE INTEGRATED RATE LAW

WebIodine Clock 6 o Thiosulfate molarity drops from [S2O3 2-]i to zero. o The I2 moles per liter consumed is [S2O3 2-]i /2 (see the balancing coefficients in Reaction 2). o The I2 consumed in Reaction 2 is produced in Reaction 1. o For each I2 mole produced, a mole of H2O2 is consumed (see balancing coefficients in Reaction 1). o Thus the H2O2 loss, … WebCLOCK REACTION . In this experiment, the effect of temperature and concentration on the rate of a chemical reaction will be studied. The reaction chosen, frequently termed the “clock reaction”, is actually a series of consecutive reactions represented by the following equations: BrO 3 1-1+ 6 I - + 6H+ Br1-+ 3I 2 + 3 H 2O (1) -I 2 + 2 S 2O 3 did einstein create the doomsday clock
