Essays on Solute

Introduction

Water is termed the ‘universal solvent’ since it is capable of dissolving a large variety of substances. These solutes can be broadly classified as ionic and molecular solutes, based on their behaviour in solution. Ionic solutes dissociate into their constituent ions when dissolved in water. An example of this class is sodium chloride (common salt). Molecular solutes are dissolved as uncharged molecules, like sucrose (sugar). The effect of ionic solutes on the boiling point of water is the focus of this project. Boiling occurs when the vapour pressure above a liquid equals the pressure over it. Hence, the normal ...

Question 1:

The Shewhart cycle also known as Deming model and the plan-do-check-act (PDCA) cycle. It is a continuous quality improvement model that is comprised of a logical sequence of the four monotonous steps to make continuous improvement and for learning. The model is considered a continuous feedback loop because it helps to identify and change the components of the process in order to reduce variation. The main aim of the cycle is to plan to do something, checking to evaluate the meeting of all requirements, and rectification of process to get desired results (Ledlow & Coppola, 2013). The four ...

Introduction

Osmosis is the process by which water molecules move from a region of low concentration of solute to a region of high concentration of solute through a semipermeable membrane (Van 3). Osmosis therefore can define the movement of water in and out of the cytoplasm of a cell. A solution with a higher concentration of solute molecules than that of the cell cytoplasm is said to be hypertonic to the cell. On the other hand, a solution with a lower concentration of solute than that of the cell cytoplasm is said to be hypotonic to the cell. Purpose: The ...

Aims

1. To observe and investigate the effects of osmosis across the cell membranes of a plant. 2. To investigate the ability of different molecules to diffuse across a selectively permeable membrane.

Introduction

All living cells are enclosed by an outer covering known as plasma or cell membranes. In addition, these plasma membranes serve as barriers between different compartments in the body to confine processes and materials to certain locations. Examples of these processes are diffusion and osmosis which are the main physiological processes that play important roles in the body. Diffusion can be defined as the process by which molecules move ...
