The ka of carbonic acid (h2co3) is 4.3 x 10–7. a solution of sodium hydrogen carbonate (nahco3) solution is created by dissolving 4.00 moles of sodium hydrogen carbonate in 2.00 l of aqueous solution. what is the ph of the solution at equilibrium?

Answerd. may include all of these are many definitions of bases: the  brønsted-lowry definition of acids and bases says that bases are proton acceptors.the arrhenius definition of acids and bases says that bases increase [oh⁻] in solution (thereby producing oh⁻ ions)the lewis definition of acids and bases says that bases donate electron pairs.therefore, the sensible answer is that a base may include all of the described characteristics.
