Experiment 7 Experiment 7 The partition of Organic acid between Water and Organic solvent Objectives Understand the partition of a solute between two immiscible solvents. Introduction A chemical analysis that is performed primarily with the aid of volumetric glassware (e.g., pipets, burets, volumetric flasks) is called a volumetric analysis. For a volumetric analysis procedure, a known quantity or a carefully measured amount of one substance reacts with a to-be-determined amount of another substance with the reaction occurring in aqueous solution. The volumes of all solutions are carefully measured with volumetric glassware. The known amount of the substance for an analysis is generally measured and available in two ways: 1. As a primary standard: An accurate mass (and thus, moles) of a solid substance is measured on a balance, dissolved in water, and then reacted with the substance being analyzed. 2. As a standard solution: A measured number of moles of substance is present in a measured volume of solution - a solution of known concentration, generally expressed as the molar concentration (or molarity) of the substance. A measured volume of the standard solution then reacts with the substance being analyzed. The reaction of the known substance with the substance to be analyzed, occurring in aqueous solution, is generally conducted by a titration procedure. The titration procedure required a buret to dispense a liquid, called the titrant, into a flask containing the analyte. A reaction is complete when stoichiometric amounts of the reacting substances are combined. In a titration this is the stoichiometric point. In this experiment the stoichiometric point for the acid-base titration is detected using a phenolphthalein indicator. Phenolphthalein is colorless in an acidic solution but pink in a basic solution. The point in the titration at which the phenolphthalein changes color is called the endpoint of the indicator. Indicators are selected so that the stoichiometric point in the titration coincides (at approximately the same pH) with the endpoint of the indicator.

The pink river dolphin, also known as the Amazon river dolphin or Boto, is one of only seven species of freshwater cetaceans. Amazon river dolphins are only distantly related to saltwater dolphins.

The sun's rays make them lose their pink pigmentation. So the darker the water, the pinker In addition, emotions like surprise and happiness can make them pinker, similar to blushing in humans! The Amazon river dolphins are very smart. With a brain 40% larger than that of humans, Amazon pink dolphins are said to be the most intelligent of the river dolphins. The pink river dolphins are friendly and there are plenty of stories of river dolphins saving people when they were in the water. 20., they have been valued by the tribes in the Amazon area for thousands of years.ood and B16.

我想請問第一題 為什麼不能是(B)的被動式 那(C)的repairing可以變名詞嗎? expensive形容詞後面接名詞

Are 33 a. Nowadays, cellphones have become a necessity in our lives. However, like other manufactured goods, they can be expensive (1) when broken. Considering how fragile some cellphones can be, they are usually used for a short period of time before being discarded without a second thought. They are also replaced as soon as new models become available. These factors have huge environmental consequences, which can only be effectively (2) by recycling. 因 完被 Ith 丟棄。 (3) has been repeatedly proven that tossing away unused electronics 再被證明 丟棄 不用の 電子產品 harms the environment. When burned or buried, the metal, plastics, and the 燒 掩埋 chemicals in cellphones release (4) pollutants into the land, water, and 釋放 污染物 +441 air. Once they're in the environment, they could cause serious damage to plants, animals, and eventually us. Furthermore, the resources needed to produce cellphones are obtained through mining, deforestation, and 採礦 砍森林 industrialization, all of which destroy the environment. 工業化 破采 These problems can be avoided (5) we recycle unwanted cellphones. Hopefully, by using recycled materials, we can better protect Mother Nature 但原願 in the age of consumer electronics. 材料 C2 De 2. (A) clustered 1.
