A neutralization process is referred to as an acid-base reply that produces a neutral solution of a salt and water. So, basically the solution obtained will have a pH of 7. well-nigh generally, the following occurs:
Acid + Base Salt + Water
For exemplar:
Hydrochloric acid (aq) + Sodium Hydroxide (aq) Water (l) + Sodium Chloride (aq)
Titration method acting was use in this experiment. Titration involves the addition of star solution to other in order to find out how much of the ii solutions just react with each other. From the results of the titration, we could calculate the assiduousness of one substance if the values for other substance are known. For acid-base reply in this experiment, we freighter find the concentration of an acid by titration with a suitable stand. The common base solution used is sodium hydroxide solution. A few types of indicator can be used to judge the end point of the titration when the cardinal solutions just react. End point occurs when a tiny wasted of OH- ions changes the indicator permanently from its comment in base into the color in neutral. In this experiment, methyl orange will 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 hydrochloric acid.
