The principle of solubility, "like dissolves like," emphasizes the importance of polarity in determining whether substances will mix. Polar molecules, such as water and ethanol, dissolve in each other due to their similar net dipoles. Understanding the polarity of various organic compounds,...
This reaction is between the lime and alkalinity of the wastewater, meaning the quantity needed will be independent of the amount of phosphate present in the water. Instead, it depends largely on the wastewater’s alkalinity and pH levels. The overall lime dose needed can be measured as 1.5 t...
How does water affect DNA structure? Structure of DNA: DNA is composed of two antiparallel strands of nucleic acids that are held together by hydrogen bonds between the nitrogenous bases of opposing strands. The backbone of each strand of DNA is composed of alternating phosphate and deoxyribose mo...
These data indicate that the concentration of nitrate and phosphate concentrations in soils can be utilized to determine the amounts and type of fertilizer necessary to maximize growth for various crop types and can be used in the development of beneficial crop rotation practices. They can also ...
During the experiment, concentrations of bioavailable nutrients were tested each week in two random tanks selected from each different plant species (Keizer-Vlek et al.2014) as well as the control to determine whether more nutrients needed to be added in order to remain within the predetermined ra...
A buffer system is responsible for keeping the pH at a specific level in which they are present. A buffer prohibits the changes in the pH of a solution due to the introduction fo an acid or a base in the solution. A buffer is formed with acid and its conjugate base in the solution....
A neutral solution of water at room temperature has a pH of 7.00. at 10 Degrees C, the pH is 7.27. What are the concentrations of hydronium ion and hydroxide ion at both temperatures? Determine the pH or pH range from the following colors of solution. ...
