Question: When a sample of hard water is passed through the layer of sodium zeolite resulting which of the following ions will not be present in the resulting sample of water obtained-
Options:
A) $ M{g^{2+}} $ and $ C{a^{2+}} $
B) $ C{a^{2+}} $ and $ N{a^{+}} $
C) $ M{g^{2+}} $ and $ CO_3^{2-} $
D) $ CO_3^{2-} $ and $ C{l^{-}} $
Show Answer
Answer:
Correct Answer: A
Solution:
[a] As $ N{a^{+}} $ ions in sodium zeolite are replaced by $ C{a^{2+}} $ and $ M{g^{2+}} $ ions present in hard water, these two ions will not be present.
