Question

How can you chemically distinguish between calcium chloride and magnesium chloride solution? ​

Answer 1

Answer:

When the two materials are compared equally (on a dry weight basis that removes all water), MgCl2 has 74% chloride while CaCl2 has 64% chloride. When the two compounds are used in equal amounts, MgCl2 thus adds about 15% more chloride to the environment than CaCl2.
