Witryna6 kwi 2024 · Silver has antibacterial and antimicrobial properties, which can kill fungi, bacteria, and certain viruses. The antibacterial action is ascribed to positively charged silver ions. These are the ones that help fight the microorganism. Silver jewelry can help with cold and flu infections and can help fight other infections. WitrynaThe core has positive charge, the electrons have negative charge. When you are rubbing the glass rod with the silk cloth, electrons are stripped away from the atoms in the glass and transferred to the silk cloth. This leaves the glass rod with more positive than negative charge, so you get a net positive charge. WitrynaThe modified colloids can be used to detect compounds which cannot be detected using conventional negatively-charged citrate or hydroxylamine reduced metal … hinckley orthodontist
