尽管IGCSE 阶段的化学知识称得上“基础”,用一句话就能概括出来:认识常见化学物质及简单的化学反应。对于刚接触的学生来说,过于庞杂的知识点,让教科书与学生间蒙上了一层纱,学生看似理解,却又模糊不清。还有的学生刚从体制内转进国际学校,第一次面对全英文的教材,

Process for the removal of a solute from a solutionThomas R Britt
Solution: A solution is made up of a solute and a solvent. A solute is a substance that is in less quantity; a solvent is a substance that is present in a greater quantity. A solute will dissolve in a solvent. Answer and Explanation: ...
If the same amount of solute is added to two solutions of different initial concentrations, the solution with the lower initial concentration will have a ___ increase in concentration. A. greater B. smaller C. the same 相关知识点: 试题来源...
To make a 1.0 % solution of a compound, how many grams would you weigh out if the final volume of solution was 500 mL? Concentration Expression: A solution is made up of a solute and a solvent. The relative amount of solute dissolved in...
solution whose concentration is accurately known. Dilution involves the addition of solvent to a solution in order to decrease its concentration. For aqueous solutions, water is added to dilute the solution. This increases the overall volume without affecting the amount of dissolved solute....
