Leading indicators

Normal standards for specific gravity are as typically as follows: 1.000 to 1.030 is a normal specific gravity, 1.001 after drinking excessive amounts of water, more than 1.030 after not drinking very many fluids and concentrated after receiving an antidiuretic hormone (ADH). Max’s urine concentration varied in concentration each time he was tested. The first test showed that his urine was a pale yellow which was an indication that he was hydrated. The second test showed the concentration to be…

The hypothesis that increasing the sucrose concentration from 6% (m/v) to 12 (m/v) would increase the rate of fermentation was not supported by the experiment. When looking at the graph it can be seen that the data obtained provided unclear results. Rather than the fermentation rate being significantly faster with a 12% (m/v) sucrose concentration throughout the entire study; the graph showed the fermentation rate for 12% (m/v) sucrose concentration was faster at times while the fermentation…

Fizzy drinks can cause some significant damage to your teeth and general heath. There are three main damaging factors: the sugar content, the acidic properties and the staining effect. The ph of a solution is defined as the hydrogen ion, H+, concentration of said solution (ThoughtCo, 2017). The ph scale ranges from 0-14. Ph 7 being a neutral ph, every ph above being classed as alkali and every ph before being classed as acidic. The mouth has a neutral ph that varies slightly from 6.5-7.5. This…

It is important to note that the goal of this experiment was to find the pKa value of bromothymol blue, a pH indicator commonly used in titrations. [UNC, 2017] The pKa is where the number of moles of acid to conjugated base are equivalent. To find this, both Beer’s Law and spectroscopy were utilized in an attempt to make graphs to show just where this value occurred. According to Sigma-Aldrich, the pKa of bromothymol blue is approximately 7.10. [SIGMA, 2017] The final pKa found experimental was…

household items that could be analyzed by titrations are fruit juice, Cola beverages and household ammonia. 3. Why is it necessary to add an indicator? Describe how an indicator works. The reason why it is necessary to add an indicator is to determine the concentration of an unknown solution. By reacting with H+ and OH-, these are weak acids and bases. If an indicator is a…

Direct titration method is a single step process. Substance is directly titrated with titrant by using simple indicator. Example: titration of strong acid (HCl) with strong base, which is usually the reactant (NaOH). 2. Indirect titration method is a two-step process. This is a titration method where the concentration of an analyte is determined by reacting it with…

The American Revolution was caused by conflicts between the colonists of America and the British government. Although the Parliament tried to keep peace and unity throughout the new colonies, the government only seemed to make things worse by creating many new laws and acts. The colonists were distressed about the new acts and decided to take matters into their own hands by rebelling in many different ways. The Sugar Act came after the Sugar and Molasses Act and was made to lessen the tax on…

As the war comes to a close and Britain feel’s the stress of postwar debt. Britain begins to look at how generous taxes are among the Americans’ and how much they are currently paying. The relationship among the colonists and Britain is both of prosper, which may have caused Britain to think the New American colonist would give in to their new regulations. Among these new regulations were the Proclamation of 1763, American Revenue Act or Sugar Act, and Stamp Act. These three laws were…

ROAD TO REVOLUTION4th Period Sophia SalibaParagraph #1 Introduction Do you know why we have the independant nation we have today? There are many reasons and events that led to what we call the Revolutionary War. These were : The Navigation Acts, the French and Indian War, Pontiac’s Rebellion and the Proclamation of 1763, the Sugar Act, the Stamp Act, Declaratory Act, the Townshend Act, the Boston Massacre, the Boston Tea Party, and the Intolerable Acts. These are the taxes and regulations…

In the testing stream water there will be nitrates, phosphates, dissolved oxygen, turbidity, different temperatures, and pH levels.The most important factor to stream testing is the temperature of the water. If the temperature increases the amount of dissolved oxygen decreases. (EPA and Staff, 2012)Phosphates are present in the water through human and animal wastes. (Oram, no date) Phosphates are used in laundry soaps, cleaners, industrial effluents, and fertilizers. (Oram, no date) Nitrates…
