Acids‚ Bases‚ and pH Lab In this lab the testing of whether or not a substance was an acid or a base occurred. Each substance was tested with the indicators red litmus paper‚ blue litmus paper‚ pH paper‚ phenolthalein‚ bromthymol blue‚ and phenol red. While the substances were tested the group noticed that the substances tested with the red and blue litmus paper‚ the phenolthatein‚ bronthmol blue were the easiest to interpret. The color changes that occurred when this indicator was put into a substance

Ammonia and Hydrochloric Acid Lab Chemistry 1 Abstract The straw should be cut shorter to 8 cm in order to make the solid ring appear in the center of the straw. We achieved our goal‚ cutting the straw caused the gases to not have to go as far‚ and meet in the middle. Background The particles in a gas are very loose and tend to move around a lot very quickly. The particles in a solid are very compact and vibrate but don’t really move very much. The particles in a liquid however are more

Acid Rain Air pollution is one of the most common outcomes of the combustion of fossil fuels. A common air pollutant that is released is sulphur dioxide and nitrogen oxides. This is because when coal and fuels obtained from crude oil are burned‚ sulpur and nitrogen is released into the atmosphere‚ which is eventually joint with the oxygen in the air to produce sulfur dioxide and nitrogen oxide. When these gases are emitted in sufficient quantities‚ it reacts with the water and oxygen in the atmosphere

THE CONTACT PROCESS By: Kabeer Ali Teacher- Mrs. Sankar Class- Lower6 Science 2 INTRODUCTION The Contact Process is the name given for the manufacture of Sulphuric Acid (H2SO4(l)). There must also be specific conditions of temperature‚ pressure and catalyst for the reaction to occur effectively. I will also look at the effect of temperature‚ pressure and catalyst on the composition of the equilibrium mixture‚ with respect to Le Châtelier’s principle. THE PROCESS Firstly‚

What is Acid Rain? First identified in 1872 in Sweden and studied in the U.S. beginning in the 1950s‚ acid rain is precipitation in the form of rain‚ snow‚ hail‚ dew‚ or fog that transports sulfur and nitrogen compounds from the high atmosphere to the ground. Sulfur dioxide (SO2) and nitrogen oxides (NO‚ NO2) are bi-products from burning fuels in electric utilities and from other industrial and natural sources. These chemicals react with water‚ oxygen‚ carbon dioxide‚ and sunlight in the atmosphere

________________________ Internal Assessment Criteria Aspect 1 Aspect 2 Aspect 3 Total DCP CE Aim: The aim of this practical is to plot and investigate the pH titration curves for the titration of a strong acid with a strong base and of a weak acid with a strong base‚ and find Ka of the weak acid. Procedure: Part I 1. Pour 30 ml of the HCl solution of unknown concentration in a 100 ml beaker. 2. Add a stirring magnet. 3. Place the beaker on the magnetic heater and activate the rotating motor but not

Chapter 4: Nucleic Acids and the RNA World 1. 4.1 – What is a Nucleic Acid? * Nucleic acids are made up of monomers called nucleotides * Three components of a nucleotide: 1. Phosphate group—attached to the 5’ carbon 2. Sugar – carbonyl group and several hydroxyl groups 3. Nitrogenous base * The prime (‘) symbols indicate the carbon being is part of the sugar—not attached to the nitrogenous base. * Four different nucleotides‚ each of which contains a different nitrogenous

Investigating the effects of acid rain in the growth of cress seedlings IntroductionAcid rain is rain or any other form of precipitation‚ which is unusually acidic. It has harmful effects on plants‚ animals and buildings. Acid rain is mostly caused by human emissions of sulphur and nitrogen compounds which react in the atmosphere to produce acids. Acid rain can slow the growth of vulnerable forests and cause leaves and needles to turn brown and fall off. In addition‚ it depletes minerals from the
