Answer #1

In the experiment, exact amount of bleach present needs to be determined. If the measurement of released O2 is not done properly, this could lead to an possible experimental error. Also, while weighing H2O2 on the balance, a steady state condition or stable reading is required. It is adviced to take the readings couple of times and repeat the experiment few times to get a good average. In case a experimenatlist fails to follow this method, may lead to experimental error in the experiment done.
