No, boric acid can still be very dangerous to humans, animals, and children. It may requires a lot of it for a lethal dose, but there are also several side effects of exposure to boric acid. Many of the insecticides that contain boric acid will contain a sweetener, such as sugar, to attract insects.
Within a water molecule is covalent bonds. between water molecules are hydrogen bonds.
Opposite charges attract one another. The slight positive charges on the hydrogen atoms in a water molecule attract the slight negative charges on the oxygen atoms of other water molecules. This tiny force of attraction is called a hydrogen bond. This bond is very weak. Hydrogen bonds are formed easily when two water molecules come close together, but are easily broken when the water molecules move apart again.
