Titration is a common laboratory method of quantitative chemical analysis that is used to determine the unknown concentration of a known reactant. The process of titration is also known as volumetric analysis of a chemical. A reagent (also known as the titrant) of a known concentration is reacted with a solution of the reactant whose concentration is not known [1]. Orange juice contains ascorbic acid. Ascorbic acid ascorbic acid (also known as Vitamin C) is antioxidant... and in presence of oxidizing agent it turns into...

...concentration at 15°C whereas at the same concentration of NaCl in PCA broth, the growth occurred. However, NaCl concentration higher than 13% in both media inhibited the growth of S. aureus. Similar behavior was observed at 18°C. With the increase in NaCl concentration, the lag phase is extended and therefore the growth rate is slowed down. c. Effect of pH value and lactic acid bacteria in milk Lactic acid bacterial starters are added for preventing the growth of S. aureus in fermented milk products such as cheese. The lactic acid bacteria ferment lactose and rapidly produce lactic... Contents Discussion 2 a. Intrinsic factors 2 b. Extrinsic factors 2 E. coli O157:H7 3 a. Temperature 3 b. pH 4 c.Water...

...acid. Concentration of tropospheric-level ozone is dependent on the concentration of the pollutants in a given area, solar radiation intensity and thermal inversions. Thermal inversion refers to the settling of warm air over cooler air near the ground level, preventing the cooler air from dispersing and scattering the pollutants (Onursal et al 19). The ill-health effects of the ground-level ozone, which forms a large part of what is visibly as smog, have been... Earth Systems 2. Explain the difference between ground- level and stratospheric ozone; why has one a beneficial and the other a detrimental role in the atmosphere? In the early phase of the earth’s history, life could only survive in the oceans ...

...ACID RAIN Acid Rain Acid rain is defined by Kumar as a term used to de "Any precipitation which has a value less than 5.6,the PH of uncontaminated water".1 In most cases, Kumar notes that acid rain falls under a PH of between 5.6 and 3.5.2 It is important to note that evidence of acidic precipitation appears after a few days and long distances from the origin. Acid rain can be prevented through a number of ways in future. According to Casper, acid rain can be prevented in future is by switching to sources of energy that emit low levels of carbon.3 Combustion of fossil...

...Concentration In this report, we describe the way light is concentrated with various optical instruments such as lenses, mirrors, and glassy (hyaline) or polymeric fiber. We analyze the tracks that light rays follow when the light has been concentrated by these optical instruments, considering any supporting equations. We analyze here converging convex lenses and the associated lensmaker’s equation; concave mirrors and the associated equation for the focal length; and optical fibers and the total internal...

...Concentration Elemental composition that is found in soils has anomalies leading to plant stress, as well as increased salt concentration (Cl-), and Ca2+ mineral nutrients. The salt concentration found in soil solutions is measured in form of its salinity. The amount of Cl- present in a given soil solution determines its salinity, which is required for proper plant life. Cac2+ is an important mineral nutrient in soil for plant life, but is harmful if in excess. The main cause of soil salinity can be attributed to the water management practices used on a given soil solution. High concentrations of Cl- destabilize membranes and denatured proteins, which is toxic for plants through soil... Soil...
