Ideally, all variables except the independent and dependent variable/variables would be controlled; however, this is not always possible. Stimulating digital resorces for the high school classroom. A bicarbonate is a carbonate with a hydrogen atom attached. The [H+] concentration is generally given as a pH value, defined as the negative logarithm: How do I choose between my boyfriend and my best friend? Begin with STC-Kindergarten, written explicitly for these standards. Hydrogencarbonate indicator can detect increases and decreases in carbon dioxide concentration. CO 2 gas has a low solubility in seawater, but it forms carbonic acid (H 2 CO 3) that can deprotonate to hydrogencarbonate ion (HCO3) and carbonate ion (CO 32 ) which together greatly increase the concentration of dissolved inorganic carbon (DIC) (eqn [1] and Figure 1 ): In eqn [1], H 2 CO 3 * refers to .
