The triprotic acid H3A has ionization constants of a1=8.14×10−2 , a2=1.93×10−9 , and a3=3.53×10−11 . Calculate the H+ concentration and the ratio [H2A−][H3A] for a 0.0100 M solution of NaH2A .

the ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (uvr) from the sun, protecting life on earth from its potentially harmful effects. when the sky is clear, there is an inverse relationship between stratospheric ozone and solar uvr measured at the earth's surface.
