1.根据文中 “Because solutions are made with water, which is made of hydrogen and oxygen, the hydrogen in the water can make a solution into an acid or a base” 可知,是水中的氢决定溶液是酸还是碱。答案是 B。 2.选项 A:文中提到 “A pH lower than 7 is more acidic”,即 pH 值低于 ...
It is possible to estimate the density of a liquid-liquid solution from the density of the solute and the solvent. However, due to shrinkage, the estimate will be a bit too low.

These materials can be added to the liquid in the batch mode or, more frequently, as a support in a chromatographic column. Tables 5.1 and 5.2 show a large number of examples of this method. The procedure that uses diatomaceous earth is generally referred to as liquid-liquid extraction. In...
Liquid vs Solution All of us are aware of liquids that that are examples of one of the three phases that matter exists in (plasma is the fourth phase). Liquids are characterized by their ability to flow and their ability to take the shape of the container in which they are placed. Water...
Circularly polarized luminescence in solution offers several advantages, however, it remains challenging for organic molecules to achieve circularly polarized luminescence with high dissymmetry factors in solutions. Here, the authors report a strategy using chiral liquid crystals to achieve circularly polarized...
To provide a step-by-step text solution for the question, "Give an example of a solution containing a liquid solute in a solid solvent," we can break it down as follows:1. Understanding the Terms: - A solute
Liquid desiccants are substances in liquid form with a high affinity to water vapor so that they can absorb water vapor in the air (i.e., dehumidifying air). From: Renewable and Sustainable Energy Reviews, 2019 About this pageSet alert ...
