  • Acids And Bases Essay

    Part A: Background Information Acids and bases are very common in today’s society, and they can be found in most households. Acids can be found as by-products of air pollution, concrete cleaner, food flavouring and is produced by the muscle. Bases are found in most cleaning products as ammonia or sodium hydroxide, and they also treat indigestion. There are many ways that acids and bases can be defined by their chemical properties. The Bronsted-Lowry definition states that acids are proton…

  • The Importance Of Agricultural Water Growth

    Because of the lack of water in arid regions, there is a great need to optimize agricultural water consumption. Thus, water conserving is becoming a decisive consideration for agriculture, particularly in arid and semi-arid regions where water is the main limiting factor for plant growth (Moftah and AL-Humaid 2005). Indeed, plants are prodigal in the water use because only roughly 5% of water uptake is used for its growth and development while the remaining 95% is lost for transpiration (Prakash…

  • How Does Ph Level Affect The Quality Of Water?

    pH Levels: The pH level system is the measure of the concentration of hydrogen ions in solutions. Subsequently, if there is a higher concentration then the pH is low meaning it’s acidic and if there’s a lower concentration then there’s a high pH levels meaning it’s basic. pH levels affect the quality of water because it affects the toxicity and the solubility of chemical substances and heavy metals. This causes the concentration of hydrogen ions in the water to change from the normal pH range…

  • Abiotic Factors Essay

    The abiotic factors that affect plant growth and development include topography, soil, and climatic factors. They are the nonliving components of the environment which, along with the biotic or living factors, determine the extent in which the genetic factor is expressed in the plant. Topography Topography is a nonliving factor that refers to the “lay of the land.” It includes the physical features of the earth such as the land elevation, slope, terrain (flat, rolling, hilly, etc.), mountain…

  • Merlot Essay

    Evaluating the benefits and problems associated with malolactic fermentation of Merlot wines Emma Bruwer, 16122364, BSc Agric (Viticulture and Oenology), J.H Neethling Building, Victoria Street, Stellenbosch University. Rudi Scholtz, Thelema Mountain Vineyards, Helshoogte Pass, Stellenbosch.

  • Seawater And Clean Water Controversy: A Case Study

    salinity level should be between 0.5 to 35 ppt. The typical pH range for an estuarine system is between 5 and 9, which is the range most finfish populations adapt to live in (pH, 2012). The main chemical species responsible for affecting the pH include the levels of oxygen and carbon dioxide (pH, 2012).…

  • Efficacy Of P. Putida And P. Fluorescens Isolates

    P. putida and P. fluorescens isolates were cultured in 250 ml Laurea Broth (LB) medium at 30±1 ºC for 36 h in an incubator shaker at 150 rpm. The culture was then poured into 50 ml falcon tubes and centrifuged for 10 min. at 6000 ×g at 4 ºC. The pellet was washed thrice in 15 ml distilled water and centrifuged. Then it was dissolved in distilled water and the optical density (O.D) of the culture was set at position-1 at 600 nm=107–108 colony forming units (CFU) ml-1 for inoculation (Bhuvaneswari…

  • Acidic Rain Lab Report

    Tables 1-6), Elodea is able to grow in combined experimental solutions with a pH level ranging from 4-5, however, once the concentrations increase the Elodea shows no signs of growth. Moreover, as concentrations increase Elodea actually decreases in length and begins to lose its color. The relationship between Nitric acid and the growth rate of Elodea in this experiment has a high validity. After calculating the averages of pH levels, experimental Elodea length and the difference in Elodea…

  • Testing Water Quality

    second step is to take it to the lab to test the water for pollutants and to test the quality of the water. Ph. is a measure of the hydrogen ion concentration of a solution. Solutions with a high concentration of hydrogen ions have a low pH and solutions with low concentrations of H+ ions have a high ph. Orange juice and coke have a low pH, but bleach and oven cleaner have a high pH ("What is pH"). Rainwater…

  • Effects Of Climate Change On Rural Communities

    1.INTRODUCTION Climate change has become one of the leading factors that has damaged rural communities in the developing world. Rural areas in the developing world are mostly affected by climate change due to lack of education and funds to implement measures that can curb climate change. Climate change has damaged rural communities by affecting the livelihood of the rural people, health, agriculture, the economy just to mention a few. Natural disasters, sea level rises and global warming are…
