S C I E N T I F I C Use this simple demonstration to illustrate the concept of diffusion. A drop of food coloring slowly diffuses in a beaker of water until the color is evenly dispersed throughout the solution. This report shows the detail of a lab project section introduction and literature review had curiosity to do research on how fast will food coloring diffuse in.
As the water and food coloring flow through the channel, they inter-diffuse along their junction. The amount of diffusion is proportional to the distance along the channel. By measuring the food color concentration profile at ten points along the channel (yielding 4 Dt for each point) and the flow rate, a value for D can be extracted.
This experiment aimed to determine how different solvents with varying molar masses affect the rate of diffusion of food coloring. It was hypothesized that lighter solvents would diffuse faster. Three solvents - hydrochloric acid, distilled water, and alcohol.
For further inquiry, maybe I can create an experiment to find the rate of diffusion as an extension to this experiment because this experiment is already about the time taken for the food coloring to diffuse with the solvents. Pace Neely Science Period 8 October 3, 2013 Lab Report #1 THE DIFFUSION LAB I. INTRODUCTION Purpose: How does the temperature of water affect the diffusion rate? Hypothesis: As temperature of the water increases the diffusion rate decreases, therefore the food coloring in the hot water will diffuse faster than the food coloring in water that is room temperature and the food coloring the in the.
This is the physics lab demo site.I6-23. Diffusion - Food Color In Water Purpose To demonstrate diffusion. Equipment Beaker of water, food coloring.
Images Description A drop of food coloring is placed gently into a beaker of water. In a few minutes the food coloring will diffuse through the entire beaker of water. It might be argued that residual currents in the water account for much of this.

The goal of this experiment is to measure the diffusion constants for two different food-coloring molecules Blue and Yellow and thus obtain the ratios of their "sizes". Fig. 2: the molecular structure of Brilliant Blue food coloring and Lemon Yellow Food coloring.
This makes, for example, water-based diffusion studies pretty easy. To measure the diffusion coefficient for blue food coloring into water. Overview: You will work with an AHT-1025A T-Sensor Lab Card (see Figure 4) which is a credit.
