All living organisms contain a certain amount of pH level. pH levels are that indicate whether a substance is acidic or basic. Acidic substances are substances that have pH level less 7 and basic substances are substances that have a pH level of greater than 7. Most living cell in the environment has a pH level of 7 which are considered to be a neutral environment. To maintain this neutral environment cells must buffer the pH level so they are not too acidic or basic (Edwards et al, 2011). Buffers are substances that help prevent the pH levels of an organism to be stable; the purpose is to maintain homoeostasis. In living organisms bodies’ pH levels are probably one of the most important elements affecting the health status and body function. pH levels reflect the events occurring in the body. pH influences every physiologic activity in the bodies; this includes metabolism, pain, and diseases. The speed of all biological and electrical reactions is under pH control. Many things in today’s environment all …show more content…
This increases the H+ activity of the solution without increasing the concentration of OH- ions in the solution. The pH of the water becomes more acidic, when increasing the drops of HCl, the pH become lower (Murmson, 2014). On average commercial buffer had a pH of 7 because when HCl was added to a commercial buffer there was no change in the pH because the commercial buffer was a weak acid, the effect of the ph will be less. As seen in figure 1 it clearly show the buffer with a constant pH of 7 compared to the other substances used. It is also because the buffer solution was composed of
The last test was called the Acidity test. The Acidity test gives us the alkalinity and acid of a stream. On the Ph scale it goes from 0 to 14. A stream with a great abundance of life will probably have a reading of 7 on the scale( which is near neutral). Here are the results from some of the tests.
This optimizes the sperm survival thus increasing chances of conception. It the ph is too acidic the sperm wont survive which will decrease the chances of
Holly Weiss SC-131 Unit 7 Acidosis and Alkalosis Assignment The normal pH value for the body fluids is between pH 7.35 and 7.45. When the pH value of body fluids is below 7.35, the condition is called acidosis, and when the pH is above 7.45, it is called alkalosis. Respiratory acidosis is a condition that occurs when the lungs cannot remove all of the carbon dioxide the body produces.
phosphates and nitrates ) - which is when fertilizers < such as those on farms > can seep through the soil or even run down the soil - called runoff - into the creek causing the water to have more nutrients than it should. ) Depending on how much pollution there is depends on how much algae there is ( the more eutrophication -there is the more nutrients in the water- results in how much algae there will be.) We were also testing on the pH scale ( which measures the acidity or alkalinity of water ) goes from 0 - 14 where 6 - 0 is higher acidity and 8 - 14 is higher alkalinity ( alkalinity is what neutralizes/destroys acid. ) 7 on the pH scale is neutral and that is the ideal water for the ecosystem. The pollution that we were testing for is where the acid came from to begin with.

Something that many can argue is sadly prevalent in our modern
I organized four different tests; pH paper, alkalinity tests, the number of rocks neutralizing acid, and the number of rocks that don’t neutralize acid. The average for pH paper was seven. The pH is the numeric scale used to specify the acidity or alkalinity of an aqueous solution. The pH scale measures acidity and alkalinity. the pH scale goes from zero, which is an acid reading, to fourteen, which is an alkaline reading.
Several other functions that it plays in the body include: balancing the electrolytes in our system, maintaining the acid-base balance and is significantly essential to muscle contraction and nerve transmissions throughout our body. A deficiency in sodium can put individuals at risk for contracting hyponatremia which is a dangerous condition in which an individual has too little sodium in their blood. The connection between sodium and water is directly correlated in keeping an equal ration of sodium and water in the body. For example, when the body contains too much salt, the body responds in keeping homeostasis by telling the individual to drink excessive water – polydipsia- until there is an equal balanced ratio of sodium to water. In addition, individuals who consume more than the recommended intake of salt tend to show signs of excessive weight gain, but in reality is just a side effect water weight in the body for this its way of maintaining a balance ratio until the salts are expelled from the body.
With the ever-changing world, it is hard to keep up with different behaviors that are typically not supposed to be in the fire
Its pH is greater than 7 and turns red litmus paper into blue. Acid- base neutralization is done by adding an acid to a base or a base to an acid until the substance has equal hydrogen and hydroxide ions. This is used to determine unknown concentration of a
Strong acids and strong bases are strong electrolytes and are assumed to ionize completely in the presence of water. Weak acids however, only ionize to a limited extend in water. Any weak or strong acids when in contact with any weak or strong alkali will start to undergo neutralization regardless of their volume. When an indicator which is present in the acid-base mixture and have experienced colour change, it indicates that the mixture is in right proportions to neutralize each other and is also known as the equivalence point.
