Acids are known to be corrosive and can cause damage when in contact with living tissue. Alkalis on the other hand are slippery and can cause burns when in contact with living tissue.

Therefore, options A, C, and D are incorrect as they do not accurately describe what happens when acids and alkalis are mixed in equal proportions.
