In contrast, dyes are either liquids or soluble, but can be converted to pigments by precipitation with a metallic salt. Is the oxygen level in my local canal enough to satisfy the biological oxygen demand (BOD) for fish? As catalysts are involved in the rate-determining step of reactions, increasing the surface area of solid catalysts should also increase the rate of reaction. It is mostly about how you treat your topic and how you present it. The enthalpy of a specific bond is defined as the amount of energy required to break one mole of the bond in gaseous molecules, calculated as an average value over a range of different molecules. How does fermentation time effect the amount of salt in miso paste, determined via argentometric titration (Volhard method)?
