Question

how to check if it is hard water with the help of soap powder

Answer 1

it will release less amount of bubbles

Answer 2

Without having to go too far out of your way, one of the easiest options for a hard water test is with a clear, clean, empty bottle with a cap, pure liquid soap and water right from your tap. Fill the bottle one-third full, add a few drops of pure liquid soap and shake vigorously for a few seconds. If there is a distinct lack of fluffy bubbles and the water appears cloudy and/or milky, your water is hard. Soft water would have copious bubbles, and the resting water at the bottom of the bottle would be clear. Keep in mind that because most soaps are formulated with detergents, they lather regardless of your water type. For the best results, use a basic soap, such as Castile, which is free of dyes, perfumes and detergents.
