(b) What experimental evidence supports your answer ?
(c)List the solutions studied that are basic?
(d) what experimental evidence supports your answer?
(e) Using these date compare the relative basicity ofca(oh)2 and C2H5NH2 . Briefly explain onwhat basis you can or cannot make comparison
(f) List the basic solutions in order of increasingbasicity
What experimental evidences supports your answer
Explanation / Answer
Answer: the solution of NaNO2 is generally basic in nature according to the given experimetal analysis .
because the formation of NaNO2 is from weak acid HNO2 and strong base NaOH thats why the solution is basic in nature .
