Method 1 visual clock reaction

WebClock reactions often appear in chemistry shows, and many involve iodine, since the colour change resulting from the generation of iodine is particularly marked. However, other chemical systems, such as the ceric/cerous/bromide reactions involved in the Belousov-Zhabotinskii reaction [1] show similar behaviour. A few clock reactions are cyclic ...

WebThe gradient gives the rate of reaction. For example, in the graph above, the rate of reaction at 300 seconds can be found. A vertical line is drawn from the 300 s mark until it meets the curve, then a tangent is drawn. Gradient 1.19 x 10 -5 mol dm -3 s -1. The gradient is the rate of reaction at that point. WebThis method starts with a solution of hydrogen peroxideand sulfuric acid. To this a solution containing potassium iodide, sodium thiosulfate, and starchis added. There are two reactions occurring simultaneously in the solution. In the first, slow reaction, iodine is produced: H2O2+ 2 I−+ 2 H+→ I2+ 2 H2O
