concentration of an acid affects the rate of the reaction. I have set up the experiment’s equipment as shown on figure 1. As you can see by figure 1‚ I have used the reaction between sodium thisoulphate solution and hydrochloric acid (HCL) to come up with results that will help me draw conclusions regarding the effects of the concentration of the acid. I decided to use this particular reaction due to the fact that the product of the reaction between sodium thisoulphate and hydrochloric acid (HCL) is precipitates

heat is given out in neutralizing sodium hydroxide (NaOH) using different concentrations of Hydrochloric Acid. Background Information:- Substances that neutralize acids are called alkalis. An acid is a substance that forms hydrogen ions (H+ ) when placed in water. It can also be described as a proton donor as it provides H+ ions. An example of an acid is hydrochloric acid (HCl)‚ Sulphuric acid (H2SO4) etc. An alkali is a soluble base and forms hydroxyl ions (OH-) when placed in water

Experiment 28: The reaction of Butanols with Hydrobromic Acid Pre-lab Objective: The objective of this experiment is to synthesize 1-bromobutane and 2-bromobutane with different catalyst:substrate ratios to determine which ratio is the most economically favorable. Discussion: In this experiment‚ 1-butanol or 2-butanol will be converted to the corresponding alkyl bromide with HBR‚ while using sulfuric acid as a catalyst. The sulfuric acid will accelerate the chemical reaction with being consumed

Diffusion of Hydrochloric Acid into Different Sizes of Agar Blocks Aim: Investigating the relationship between the diffusion and the surface area to volume ratio‚ with agar and hydrochloric acid. Research Question: How does the difference in surface area to volume ratio affect the diffusion? Hypothesis: As the area to volume ratio increases‚ the time taken for a complete diffusion will also increase. Background Information: Agar is a jelly like substance and in this experiment‚ agar

Factors affecting learning MATURATION AS FACTOR IN LEARNING Maturation is an important factor that affects our learning is defined as “growth that proceeds regularly within a wide range of environmental conditions.” Maturation is growth that takes place regularly in an individual without special condition of stimulation such as training and practice. Learning is possible only when a certain stage of maturation is also reached. Exercise and training becomes fruitful only when a certain stage

Factors affecting healthy development in children There are many different factors that affect a child healthy growth and development. Knowing the different factors that can affect the child enables us to differentiate activities suited to all children and also if need be place areas of concern so there is early intervention and then that the child has the best possible start.

Physics IA A factor affecting Spaghetti Jonathan Dean Scotch College 28/03/13 Design Introduction The aim of this experiment will be to conduct an investigation into a factor of spaghetti. Such factors include how the diameter will relate to the flexibility of the spaghetti‚ or how the carbohydrate content will relate to the flexibility. For this experiment‚ the carbohydrate content and how it relates to the flexibility will be investigated. Flexibility will be determined by the angle
