You may have heard lately about HW or hydrogen water. I’ve had several texts and emails asking for my take on it. To begin, I need to back up and remind you of some high school chemistry. I nearly burned down the lab when something I want working on blew up. No one was hurt but I decided definitely not to become a chemist! An ion is an atom or a group of atoms with an electric charge. Positive ions, or cations, are formed by the loss of electrons; negative ions, or anions, are formed by the gain of electrons. You may recall that atoms typically have two electrons. The hydrogen ion or atom is composed of 1 proton and 1 electron and carries a weak positive (+) charge.
