Introduction Background Information To begin a discussion about acid-base titrations‚ we must first recall that there are several definitions of acids and bases. For the purpose of this exercise‚ we will consider the Arrhenius definition of acids and bases‚ in which an acid is a proton (H+) donor and a base produces hydroxide (OH-) in solution. When an acid reacts with a base‚ the products of this reaction are water and a salt. Note that salt here does not only mean table salt (NaCl)‚ but can refer

Introduction A melon is any of various plants of the family Cucurbitaceae with edible‚ fleshy fruit. The word "melon" can refer to either the plant or specifically to the fruit. Many different cultivars have been produced‚ particularly of muskmelons. Although the melon is a botanical fruit (specifically‚ a berry)‚ some varieties may be considered vegetables rather than fruits. The word melon derives from Latin melopepo‚ which is the latinization of the Greek μηλοπέπων (mēlopepon)‚ meaning "melon"

1. Aim: To determine the weight-to-volume percent of acetic acid present in commercial vinegar and the weight-to-volume percent of ammonia present in window cleaners. Acid-base titrations can be conducted using the above samples against standardized aqueous NaOH and standardized aqueous HCl solutions respectively. 2. Introduction: Acetic acid‚ commonly known as ethanoic acid CH3COOH‚ is found in commercial vinegar. It is a weak organic acid that gives vinegar its characteristic pungent smell‚
