Does calcium chloride react with sodium hydroxide?

28/2/2020· Calcium chloride react with sodium hydroxide to produce calcium hydroxide and sodium chloride. Besides, does calcium react with Naoh? No calcium metal can''t reacts with sodium hydroxide because sodium is more reactive than calcium which means sodium has higher tendency to lose electron than calcium that''s why calcium can''t displace sodium from its aqueous solution.
