Soaps form foam with hard water or soft water?
Naomi AronsonSoft water
When soaps are used in soft water, they foam up quickly. However, when soaps are used in hard water, they take longer to neutralize the calcium and magnesium ions and first lather.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
