Download file to see previous pages The colour change in observed in each of the solutions was recorded and later used to determine if the solutions were either basic or acidic. From the experiment on PH, it was observed that despite the different outputs of the indicators the colours and digital signatures tally with standard conventions even when verified against an electronic PH probe.
Conductivity measurement can be utilized in the surveillance of purity of feed water, quality control of drinking water and process water. It estimates the total number of ions in a solution or directly measures the constituents of the sample. Conductivity instrumentation is highly reliable, low cost and very sensitive (Gray, 2006 p.1). The conductivity of water provides information on its chemical composition as it is directly linked to the concentration of ions and their mobility (Dalmas, n.d, p. 1). From figure 1, it is observed that as the concentration of ions in a solution increases so does the conductivity.
Conductivity measurements are based upon the Measurement of electric current flowing between parallel plates of fixed size and fixed separation distance (leveling, 2002. P. 1). Electrical conductivity is dependent on the PH, temperature and dissolved carbon dioxide. Conductivity can either be intrinsic or extraneous. It has been reported that soil solutions presenting high concentrations of sodium chloride with electrical conductivity of between 6 to 10 mmho/cm can be associated with a 50% decline in rice yield and in addition high PH of alkaline soils induces zinc deficiency (Breemen and Moorman, p.121).
pH is a measure of the acidity or alkalinity of the solution and is measured by determination of the concentration of hydrogen ions (H+) or hydroxyl ions (OH-) present in the solution. The assembly of a pH meter comprises of a pH sensitive electrode that is commonly made of glass, a reference electrode, and a temperature element that ...Download file to see next pagesRead More

Radiation and Thermal Conductivity
...for the thermal conductivity of the system, Aint stands for the surface area which is computed from the diameter of the sample, ?Tint stands for difference in temperature between the cold surface and the hot surface and Xint stands for the distance between the cold surface and hot surface. Methodology All of the experiments were done in the lab where the thermal radiator was connected to both the power meter and the hot plates. The hot plates had thermocouples placed inside them. The first experiments involved the collection of data to determine the relationship between F and the radiation intensity, in the second experiment a thermal radiometer shown in figure 1 was placed at a distance of 900mm from...

...or the states that affect the levels of hydraulic conductivity. Further, the paper will explore the importance of hydraulic conductivity and the methods used for the determination of hydraulic conductivity using empirical-based, field-based and lab-based approaches. The properties and the states that affect hydraulic conductivity The first property is the compaction conditions of the soil or the rock materials, where the difference in hydraulic conductivity depends on the contours of initial saturation. The zones of initial saturation are computed using the following equation: (Brauns, Bieberstein & Reith, 2003) Under the equation, “w is...

PH Titrations
...? PH Titrations Background Titration or titrimetry involves a method of laboratory that is used to analyze chemicals quantitavely and to determine the concentration of the unknown solution. The process is depended on the volume of a solution, a process that is referred to as volumentric analysis. A standard solution is defined as a reagent. In most cases, a concentration that is known reacts with the titrant volume to establish the concentration. Titration involves a group of experiments in which the known solution property is utilized in inferring to the unknown property of a different solution. In the chemistry of acids and bases, titration is used in determining the value of pH for different solutions...

PH Titration
... pH Titrations Background: In general, titration refers to an experimentally conducted process in chemistry lab, normally for the purpose of determining substance concentration of interest in a solution. Typically, acid-base titrations are applied in order to estimate the molarity either of an acid or a base used through a setup that consists of a burette that holds the ‘titrant’ and flask filled with ‘analyte’ or the solution with unknown concentration. During titration, it is essential to figure out the ‘equivalence point’ where moles of acid and moles of base added become equivalent. To aid an experimenter in this situation, a halochromic organic compound known as ‘indicator’ (s.a. phenolphthalein, methyl red, methyl orange... - titrant...

Acids' Alkalis and PH
...is a weak base. 3 marks 5. Find the pH of the following solutions assuming complete dissociation: a) 0.010 mol dm-3 HCl (1) HCl is a strong monoprotic acid; it fully dissociates into H+ and Cl-. [H+] = 0.01 mol dm-3 pH= -log 0.01= 2 b) 0.00333 mol dm-3 H3PO4 (2) H3PO4 is a triprotic acid. Complete dissociation would give 0.01 mol dm-3 [H+]. [H+] = 3 x 0.00333 mol dm-3 = 0.01 mol dm-3 pH = -log 0.01 = 2 As H3PO4 is an acid with medium strength, full dissociation of the three protons will not happen in practice. Exact values of [H+] and pH can be only obtained by using the Ka1, Ka2 and Ka3 values of H3PO4. c) 0.75 mol dm-3 H2SO4 (2) H2SO4 is a strong...

Hydraulic Conductivity in Soils
...Hydraulic Conductivity in Soils Hydraulic Conductivity in Soils Bi-modal soils are the soils that have structural and matrix porosity (Dexter & Richard, 2009). In these bi-modal soils there is a model for water retention which is developed into other models such as the tri-modal soils (Dexter & Richard, 2009). Such a change ensures there is an incorporation of the existing effects of macro-pores. Additionally, the bi-modal soil model has its basis on the idea of water retention function of the exponential Boltzmann. Researchers also believe that the model can also extend to include other numbers such as the “n” of the modes of porosity. These modes exist because the soil structure is usually hierarchical. It is also used together... with...
