What experiment would i carry out to find the fluoride content of different toothpastes? Is there a specific test for it?
Corrie writes …. Fluoride ions are difficult to detect since they are relatively unreactive they cannot be easily oxidised for example and there are no straightforward class lab tests available. There are commercial test papers available for the detection of fluoride ions, but the chemical processes involved are highly complex, and in any case are not appropriate for use in a school or college lab. However, here is a website that details a method for determining fluoride in toothpaste that may be useful to you. http://www6.cityu.edu.hk/bhdbapp/student/POP/CYMCA-Fluoride.ppt Click on the pages and the text will appear. Risk assessment Before attempting any practical work based on the advice and suggestions on this website, you must do the following. Identify any hazards, assess the risks from these hazards, and then decide appropriate control measures to reduce the risks. You must have these approved by those in authority in your school or college laboratory. Do not rely on what is sa
