Answer:
to make a hard water at home ....
Wear protective glasses and rubber gloves. Pour 500 milliliters of distilled water into a calibrated beaker, water level touching the 500 milliliters mark in the beaker.
Add half tablespoon of epsom salt to the distilled water. Stir well to completely dissolve the salt and make a clear solution. Calcium chloride increases the permanent hardness of water.
Add half tablespoon of baking soda to the solution. Stir the solution well to completely dissolve the baking soda. Baking soda generally increases the temporary hardness of water.
Add half table spoon calcium chloride to the solution and stir to completely dissolve calcium chloride in the solution. Calcium chloride increases the permanent hardness of water.
Leave the solution for few hours. Generally 2 hours of time will be enough for complete dissolution of the minerals into the solution.
Make a filter cone with the filter paper. Filter the solution slowly with a the filter cone into another beaker to remove any suspended material.
