A125.0 mg sample of methylamine (ch3nh2 mw = 31.06) was dissolved in 25.00 ml of carbonate-free water. {the ka for ch3nh3+ is 2.3 x 10-11.} determine the ph of the resulting solution after the addition of each of the following solutions. (treat each part separately, not as a sequential addition of a then b then c.

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.
