DETERMINATION OF THE SOLUBILITY PRODUCT CONSTANT OF CALCIUM HYDROXIDE ABSTRACT This experiment aimed to determine the solubility product constant (Ksp) of Ca(OH)2 as well as to evaluate the effects of common and non-common ions on its solubility. Ca(OH)2 solids were dissolved in eight various media: distilled water‚ 1.0 M KCl‚ 0.5 M KCl‚ 0.1 M KCl‚ 0.05 M KCl‚ 0.005 M KCl‚ 0.001 M KCl‚ and 0.1 M Ca(NO3)2. The concentration of dissociated OH- concentrations was determined by means of titrimetric

Lines of Latitude are parallel to the equator. True Lines of longitude are parallel to the polar axis. True What is the approximate diameter of Earth at the equator? About 8‚000 miles “Time” can be used to calculate latitude. False Why is it difficult to produce a 2-dimensional map of the earth that will faithfully reproduce to entire earth surface without distortion? There is no way to produce such a map because of the shape of the earth. According to Oceanography‚ Which of the following was the

EXPERIMENT 2: SUSPENDED SOLIDS 1.0 OBJECTIVE This objective of this experiment is to determine the quantity of suspended solids in polluted water samples. 2.0 INTRODUCTION Water quality is vitally important in our daily life. However‚ due to water pollution‚ the quality of water is questionable for safe usage. In order to determine water quality‚ one of the indicator and measurement that can be used is by suspended solids (SS). Suspended solids is one type of physical water-quality measurement

Pollution Introduction Pollution is the introduction of contaminants into an environment that causes instability‚ disorder‚ harm or discomfort to the ecosystem i.e. physical systems or living organisms. Pollution can take the form of chemical substances or energy‚ such as noise‚ heat‚ or light. Pollutants‚ the elements of pollution‚ can be foreign substances or energies‚ or naturally occurring; when naturally occurring‚ they are considered contaminants when they exceed natural levels. Pollution became

Impacts of Ammonia Ammonia impacts both the environment and human health. * Environmental Impacts * Human Health Impacts Environmental Impacts When in gaseous form‚ ammonia has a short atmospheric lifetime of about 24 hours and usually deposits near its source . In particulate form ammonia can travel much further impacting a larger area. Both gaseous and particulate ammonia contribute to eutrophication of surface waters‚ soil acidification‚ fertilization of vegetation‚ changes in ecosystems
