Trending Questions. Strong acids such as hydrochloric or nitric acid at concentrations up to 10% are the most rapid in action but if used for an excessive time will rapidly cause a loss of nuclear staining and can macerate tissues. bone, middle contact zone (CZ), and mineralized matrix (MM) in the endosteal part of bone.
