Brönsted acids: conductivity comparison of molten and dis-solved oxalic acid Principle Acids in the form of solids or melts do not conduct the electric current. Since acids in the form of aqueous solution do conduct the electric current, they must be present in the form of charged particles (ions) in this case. In this experiment students study the conductivity of molten oxalic acid and of a solution of oxalic acid. Learning objectives - Conducivity of acids in different state
Benefits - Easy teaching and efficient learning by using interactive experimentation PHYWE-Software
- Experiment is part of a complete solution set with experiments for the topic acids, alkalis and salts matched with international curriculum: all topics are covered
