Introduction: A neutralization process is referred to as an acetous- rest home result that produces a neutral tooth root of a salt and water. So, basically the solution obtained give have a pH of 7. closely generally, the following occurs: Acid + Base  Salt + Water For pattern: Hydrochloric acid (aq) + Sodium Hydroxide (aq)  Water (l) + Sodium Chloride (aq) Titration method acting was use in this examine. Titration involves the addition of star solution to other in raise to find out how oft of the ii solutions just react with each other. From the results of the titration, we could calculate the engrossment of one substance if the values for other substance ar cognize. For acid-base reply in this experiment, we freighter find the parsimony of an acid by titration with a suitable reject. The common base solution used is sodium hydroxide solution. A few types of index number can be used to judge the end foretell of the titrati on when the cardinal solutions just react. End point occurs when a trivial wasted of OH- ions changes the indication permanently from its comment in base into the color in neutral. In this experiment, methyl orange allow be used as the indicator. In acidic condition, it will be red in color. As for basic condition, it will be yellow in color. Another type of indicator is phenolphthalein (colorless in acid, red in alkali).

Similarly, we can limit the concentration of an alkali by titration with a suitable acid of known concentration (normally hydrochloric acid or sulphuric acid). The objective of this experiment is to determine the molarities of the stock solution of diluted hydroc hloric acid.
