The marketing slogan 'consumes 47 times its weight in excess stomach acid solution' has long been used in Rolaids" advertisements. Is this claim true? In other words, what mass of stomach acid solution does a Rolaids" tablet neutralize and is this mass 47 times greater than the mass of a Rolaids™ tablet? Assume that stomach acid solution is 0.137 M HCI. Also assume, since it is mostly water, that stomach acid has a density of 1.00 g/mb.

Hazard Analysis and Design in Chemical Engineering

Hazard is the intrinsic property of a material or process which harms the people, buildings, or environment. Health, safety, hazard, risk assessment, loss prevention, and environmental consideration play an important role while designing a chemical processing plant. Hazard is often confused with risk. Risk measures the magnitude of loss and injury of likelihood incidents or the consequence and frequency of incidents.
