Answer:
(a) false, (b) true, (c) true and (d) false
Explanation:
HA is a strong acid. Hence it dissociates completely to produce equal amount of [tex]H^{+}[/tex] and [tex]A^{-}[/tex] as follows:
[tex]HA\rightarrow H^{+}+A^{-}[/tex]
Hence no HA will be left in solution.
[tex]pH=-log[H^{+}][/tex] , where [tex][H^{+}][/tex] represents concentration of [tex]H^{+}[/tex] in molarity
Here, [tex][H^{+}]=1.0M[/tex]
So, [tex]pH=-log(1.0)=0[/tex]
Hence, (a) false, (b) true, (c) true and (d) false
