20、idney and the acid base balance it regulates is nearly infinite,which means that while it works relatively slowly,it can COMPLETELY correct for abnormalities in pH.The“metabolic”or renal regulation of the balance of H+or HCO3-excreted will determine if there is a net loss of H+or HCO...
I. Formation of Solutions A. Dissolving 1. Solute – substance that is dissolved in a solution 2. Solvent – the substance that the solute dissolves in Ex. coffee sugar is the solute and the water is the solvent, Air → N is the solvent b/c it makes up about 78% of air...
proton from an acid to a base. In an acid-base reaction, one bond is broken, and another one is formed. The electron pair of the base B: forms a new bond to the proton of the acid. The acid H—A loses a proton, leaving the electron pair in the H—A bond on A. Acids and ...
