None because Covalent compounds don’t conduct electricity because they are formed between the non metal atoms by sharing of electrons. The Covalent compounds haves no free electrons and also no ions and hence they do not conduct electricity. That is why they do not conduct electricity.
More than likely, your seeing a chemical reaction. The bubbles that are forming are caused by two compounds interacting with each other.
