Introduction: The Mohr method is the method used to determine the chloride ion concentration of a solution by titration with silver nitrate. As the silver nitrate solution is slowly added‚ a precipitate of silver chloride forms. Ag+ + Cl- AgCl(s) (Ksp for AgCl is 1.810-10) The chloride ion (Cl-) is an important anion found in solids and solutions. Chloride is the predominant anion of sea water with a molarity of approximately 0.54M. Therefore‚ it is an essential component of fluid systems in the

the ksp. The solubility product constant can be calculated using the equation: Ksp = [k+][HC4H4O6-]. On the other hand‚ the solubility of a compound refers to the concentration of a solute in equilibrium with undissolved solute in a saturated solution. In this experiment‚ the solubility and the solubility product constant in water of KHT was determined. The concentration of HC4H4O6- in solution can be determined by the direct titration of a filtered solution with a standard sodium hydroxide solution

In The Catcher in the Rye by J.D. Salinger there are many insights about Holden Caulfield revealed by symbols‚ which would otherwise remain unclear. School‚ the checkerboard‚ the museum‚ and cigarettes and alcohol are all symbolic of Holden. These symbols tell us things about Holden that he doesn’t tell us straight out. This essay will discuss many symbols in the book and what they tell us about Holden. The checkerboard is referred to a lot when Holden is thinking of his old friend Jane Gallagher

The equation for the reaction between a free calcium ion and an EDTA compound in pH of 10 is a 1:1 reaction which allows to see how many calcium ions were stabilized and therefore dissociated from the CaC2O4. This number of moles can then be multiplied by the molecular mass of CaC2O4 to find the initial weight of the ions that dissociated which

E.B. White’s essay‚ "Once More to the Lake‚" ends with his feeling "the chill of death." This phrase is a haunting and initially abrupt end for the essay‚ especially since on first reading the essay seems to be merely a pleasant description of a lakeside vacation. With a little attention‚ though‚ it’s easy to see how the essay leads naturally to a sense of death’s approach or inevitability. On the literal level‚ White feels an actual chill.
