Acid-base homeostasis

was measured and labeled from a strong base to a very strong acid. Then, react one of the unknown solution with all of the others and note any visible reaction (change in color or formation of precipitate) that occurs. After that, some the solutions might be identified throughout the…

there is an unknown solution (analyte), titrant is used for identifying the concentration of that unknown by adding titrant to analyte. (using burette) Acid –base indicator: acid- base indicator is an indicator that determines the pH of a solution by changing its color due to H+ ion concentrations inside the solution. Indicator range: acid- base indicators change their colors when pH changes. However, they are useful in a specific pH interval. pH of a solution cannot be determined if pH is out…

electrolytes in their cell structures. In humans this balance is regulated by hormones. Disruption of this balance leads to health problems. Electrolytes are useful for electrical batteries and fuel cells. Electrolytes commonly exist as solutions of acids, bases, or salts. Some gases act as electrolytes under conditions of high temperature of low pressure. Solutions are formed when a salt is placed into a solvent such as water. An electrolyte solution may be described as concentrated if it has a…

What are buffer solutions? Buffer solutions are solutions in water that mark the mixture of acids and bases. They assist in neutralization response to a certain quantity. Acidic buffer answers are those that have robust acids and weak bases as their components. they're used for neutralizing alkaline solutions. Alkaline or primary buffer answers are those who have sturdy alkalis and weak acids within themixture. they're used for neutralizing acidic aqueous answers. Buffer solutions in the blood…

In step d) 10cm3 of dilute hydrochloric acid is added to the separating funnel containing paracetamol, caffeine and ethyl acetate mixture. This protonates the caffeine which therefore gives it a positive charge allowing it to be soluble in the hydrochloric acid aqueous layer whereas the paracetamol stays in the ethyl acetate, since the two mixtures, ethyl acetate and hydrochloric acid do not mix then the caffeine is separated from the paracetamol and ethyl acetate…

acidic. The mouth has a neutral ph that varies slightly from 6.5-7.5. This ph is maintained by buffers in the mouth, particularly in saliva. Buffers are solutions made up of either a weak acid and its salt or a weak base and its salt. They are used to resist the ph change in a solution when small amounts of acids or bases are added.…

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…

This morning, an airman on Lackland Air Force Base (AFB) just outside San Antonio, Texas shot and killed his squadron commander, then killed himself. At this time, it is unclear on the reasons for the incident. But it once again brings up the question, should military personal be allowed to be armed at all times to protect themselves? The active shooter incident on Lackland marks the 10th fatal shooting on a U.S. military installation in the U.S. since 2001. Of the 10, 3 have been confirmed…

to as acid rain and more properly known as acid deposition. This research will thoroughly examine acid rain, it’s causes, the effects on the environment, and some possible solutions to slow the damage. Acid rain is simply rain that is acidic. This rain comes in many forms that include some dry and wet deposition. The smog that you see above cities is actually a dry form of acid rain. Pure…

IONIC LIQUIDS Introduction:- Ionic liquids are actually salts that are liquid in state, normally referred to compounds that have melting point below an arbitrary temperature i.e. 100° C. Unlike some other ordinary liquids like water and gasoline, that are composed of neutral species while ionic liquids are composed of ionic species and ionic intermediates commonly known as “ionic fluids” and “liquid electrolytes”. In ionic liquids there is a species that has a delocalized species and the other…
