Polycarbonate is a versatile, tough plastic used for a variety of applications, from bulletproof windows to compact disks (CDs). The main advantage of this material over other types of plastic is its great strength combined with light weight. While acrylic is 17% stronger than glass, polycarbonate is nearly unbreakable.
Bicarbonate (HCO 3 â) is alkaline, and a vital component of the pH buffering system of the human body (maintaining acid-base homeostasis). 70-75% of CO 2 in the body is converted into carbonic acid (H 2 CO 3), which can quickly turn into bicarbonate.he prefix bi in bicarbonate comes from an outdated naming system and is based on the observation that there is two times as much carbonate (CO 3) per sodium ion in sodium bicarbonate (NaHCO 3) and other bicarbonates as in sodium carbonate (Na 2 CO 3) and other carbonates.
