When calculating the concentration of H3O* ions for polyprotic acids, the reaction occurs in steps. Which statement below best describes the multiple Ką values that follow the first K₂? Multiple K₂ values are used to support quantitative observations fundamental to analytic chemistry. Multiple K₂ values are used to maintain accuracy and precision. Multiple K₂ values are seldom used, as their contribution to the concentration of H30+ ions is very small. Multiple K₂ values are seldom used, as an approximation of pH is suitable for most purposes.
