Acid-Base Calculations The Ion-Product Constant for Water‚ Kw Water undergoes ionization to a small extent: H20(l) H+(aq) + OH–(aq) The equilibrium constant for the reaction is the ion-product constant for water Kw: (1) This is a key equation in acid-base chemistry. Note that the product of [H+] and [OH–] is a constant at a given temperature (Eq(1) value is for 25oC). Thus as the hydrogen ion concentration of a solution increases‚ the hydroxide ion concentration decreases

As William Pitt once said‚ “ Unlimited power corrupts the possessor.” This quote represents the main theme of Animal Farm By George Orwell. In the novel the animals from a farm want to have freedom from the humans‚ after they get their freedom it does not turn out as how they imagined it. George Orwell gives the the theme of how power corrupts people or in this case animals in his novel. At the beginning of the novel the animals established Seven Commandments that they were going to live by but

TACTICS AND STRATEGIES FOR SUCCESS IN WAR. The American civil war was one of the toughest and deadliest wars in American history. This was where the Confederate States of America fought for their independence. It took place from 1861 when the war broke out till April 9th 1865 when confederate commander Robert E. Lee surrendered at the McLean House in the village of Appomattox Court House. It was one of the earliest true industrial wars. Industrial knowledge was used to produce weapons in mass-production

What principles of supportive communication and supportive listening are violated in this case? I believe that there were a number of violated principles of supportive communication and supportive listening that occurred in the case of “Find Somebody Else.” The conversation between Ron Davis‚ a relatively new general manager and one of his current plant managers‚ Mike Leonard‚ brought out few raised eyebrows; however‚ I personally had a number of similar experiences. In my opinion Ron could

In order to be given this opportunity‚ Locke believes it is first necessary to establish a Legislative power for the good of all members of a society. The legislative power is to promote and guarantee preservation of all natural rights including safety for every person among the society. This legislative power thought does not have an absolute power‚ instead the power is offered based on the decisions as a majority given by the members in that society. This procedure is used so that any

Experiment Acids‚ Bases‚ and Neutrals Problem Are common house-hold products pH balanced and neutral? Information Gathered pH measures how acidic or alkaline a solution is. The pH scale ranges from 0-14. Solutions that range from 0-6 are considered to be acidic. Solutions that are on the acidic end of the scale are low in pH‚ high in hydrogen ion‚ and low in hydroxyl ions. An acid has a sour taste‚ hence‚ will react to metal and will be corrosive; therefore‚ they are considered as an electrolyte
