Recommended: Essays on acids and bases

pH stands for "Potential Hydrogen", pH is the most basic and fundamental driving force of all our body function. You may be wondeering what ions are responsible for making a solution an acid or a base. It is simple, Acids produce hydrogen ions H+in a water solution while Bases produce hydroxide ions OH- in a water solution. an example for an acid is HCl and an example for a base is NaOH. The pH scale measures how acidic or basic a substance is. It ranges from 0 to 14. one through 6 being acidic, 7 being neutral, and eight through 14 being bases.

The three theories that outline the definition of an acid or a base are The Arrhenius Theory, The Bronsted-Lowry Theory, and The Lewis Theory. There are three different theories are used to define

    More hydrogen ions in a solution is a result of lower pH, while fewer hydrogen ions in a solution is a result of increased pH. Meaning that a lower pH level results in a higher enzyme activity reaction and a higher pH level results in a lower enzyme activity reaction (Christianson, 2011 ).

    Acids and Bases can be very similar. Acids, when mixed with water free hydrogen ions. Bases, when mixed with water free hydroxide ions. In both cases, Acids and bases, the freeing of ions is called dissociation. Although there can be rich solutions and poor solutions. Acidic is a solution that is very rich in

    Lavoisier made-up that all acids must comprise oxygen, and this idea was combined in the names used for this element in the various languages; the English oxygen, from the Greek oxys (sour) and genna (production); the German Sauerstoff, literally acid material; and the Russian kislorod, from kislota (acid). Succeeding the discovery that hydrochloric acid confined no oxygen, Sir Humphry Davy about 1815 first known that the key element in acids was hydrogen. Not all substances that hold hydrogen, however, are acids, and the first really reasonable definition of an acid was given by Justus von Liebig of Germany in 1838. According to Liebig, an acid is a compound having hydrogen in a form in which it can be replaced by a metal. This definition held the field for about 50 years and is still deliberated essentially correct, though somewhat outmoded. At the time of Liebig’s proposal, bases were still stared solely as substances that neutralized acids with the production of salts, and nothing was known about the constitutional features of bases that enabled them to do

    Chemists have known for some time that the H+ ion doesn’t exist in aqueous solutions as an independent species. The modernized Arrhenius definition of acid is that they are substances that produce H3O+ ions in aqueous solutions. It did not take longer for chemist to find other problems with the Arrhenius definition. In practical terms, the OH- ion is far from being the only base.

    Acids are a material that releases a proton or hydrogen ion (H+). Acids always generate an H+ whenever the solution is aqueous, which can be easily identified. On the contrary, in an aqueous solution involving bases always produce an OH- ion. There are many different ways to identify whether a substance is an acid or a base. An acid is always sour, changes litmus, conduct an electric current, react with a base to form salt and water, and whenever there is a reaction, acids helps advance an hydrogen gas with an active metal, such as the alkaline earth metals, zinc, and many more. Some well known or common acids are citric acid, which are from citrus fruits, such as oranges, lime, and lemons. Vinegar and carbonic acid (soda/soft drinks) are also some common acids. Bases are the opposite of acids. They can be identified by their bitter taste, soapy or slippery feeling, and cannot change the color of litmus. Bases can become red litmus to reverse back to the blue litmus. Similarly, acids and bases conduct an electrical current in an aqueous solution, thus they are...

    The simplest experiment for this type of situation would be to use red and blue litmus paper to distinguish between acids, bases and salts. Hydrochloric acid (HCl) makes blue litmus paper change color going from blue to red, making it an acid. Sodium hydroxide (NaOH) makes red litmus paper change color going from red to blue, making it a base. Sodium chloride solution (NaCl) is neutral, since it would only soak blue and red litmus paper, considering that it is a by product of when an acid and a base mix together, neutralizing each other.

  • 5 Characteristics Of Living Organism Essay

    A buffer is important to the pH of living system because, the buffer helps keep our body fluids within normal limits. In all living organism the pH of bodily fluids has to stay within normal limits for any organism to maintain life. If a living organism has hydrogen ion concentration level is too high, it will be too acidic or too low on the pH scale. Likewise, if the organism’s hydroxide ion concentration is too high, it will be too basic or too high on the pH scale. If this occurs, it can affect the living organism’s life. An example of this is human blood on the pH scale. The pH level of our blood, when we are healthy is 7.4; which is slightly basic (alkaline). If blood increases on the pH scale it can be life threatening; likewise, if blood decreases on the pH scale below 7.0, it can be life threatening. In order to keep blood at 7.4 it has to have stability that our body has; and a buffer is an essential mechanism to keep blood at a safe level.

    The colour of the acidic solution turned a reddish-pink indicating a low pH whereas the colour of the alkaline solution turned blue-green indicating a high pH, the colour of the solution with an addition of water remained the same, and therefore the hypothesis is supported. The experiment can be improved by using pH strips to get the actual pH value thus allowing the experiment to be more accurate.

    An acid is a substance that corrode things and gives things a sour taste to them when comcumed. The word acid comes for the Latin word acidus, which means sour. An acid that can conduct electricity is called an electrolyte. When an acid conducts electricity the electrons are passed through each atom and so on. To test whether a substance is an acid or not, use a litmus paper. The litmus paper can identify acids. During production the litmus paper, that contains wood cellulose, with a chemical that is extracted from some other lichens. If the substance is an acid it will turn the blue litmus paper to red. Also, an acid can be identified by its chemical properties. Acids react with metals to produce salt and hydrogen.
