the pH of Distilled water‚ Potato Solution and Commercial Buffer‚ when Hydrochloric acid (0.1 mol/L) and Sodium Hydroxide (0.1 mol/L) is added Mahima Mandava Mrs. Haist September 23rd‚ 2014 SBI4U1 Background Information: The pH is the measurement of how acidic or how basic a substance can be. The pH scale is used to measure how acidic or basic a living cell can be. The pH scale ranges from 0-14; 0-6 being acidic‚ 8-14 being basic and 7 being neutral. There are many factors that could

Acids and Bases Are Everywhere Every liquid you see will probably have either acidic or basic traits. Water (H2O) can be both an acid and a base‚ depending on how you look at it. It can be considered an acid in some reactions and a base in others. Water can even react with itself to form acids and bases. It happens in really small amounts‚ so it won’t change your experiments at all. It goes like this: 2H2O --> H2O + H+ + OH- --> H3O+ + OH- See how the hydrogen ion was transferred? Most of the

Preparation and melting point of Aspirin Aspirin is a painkilling drug and is produced worldwide to reduce and stop pain. Aspirin is made up of ehtanoylation of 2-hydroxbenzenecarboxylic acid in a presence of phosphoric acid. AIM: The aim of the experiment is to prepare and produce aspirin as pure as possible. I will do this threw preparing the aspirin and purifying the product threw recrystallization. I will then obtain a melting point of my product to get an estimate of its purity. By the end

of sodium thiosulfate can be used for cleaning contact lenses and used as a medicine for some cancer patients. Concentrated solutions are used to treat spillages of some chemicals. Sodium thiosulfate is safe to handle and store‚ but if it is mixed with an acid‚ a reaction happens. When dilute sodium thiosulfate is mixed with an acid‚ solid sulphur is made‚ which makes the solution appear cloudy. The reaction also makes small amounts of toxic sulphur dioxide gas. You will choose one factor and investigate

but first you have to produce sulphur dioxide. Stage 1: Making sulphur dioxide Either burn sulphur in air: S (s) + O₂ →SO₂(g) Or heat sulphide ores strongly in air: 4F eS₂(s) + 11O2(g)→2F e₂O₃(s) + 8SO₂(g) Stage 2: Making sulphur trioxide Now the sulphur dioxide is converted into sulphur trioxide using an excess of air from the previous process. 2SO₂ + O₂⇌2SO₃(g) △H =− 196kJ mol ¹ Anissa Davis 32130161 Further reactions In this reaction an excess of oxygen is used

Amino Acids Amino acids are biologically organic compounds containing amine and carboxylic acid functional groups‚ usually along with a side-chain specific to each amino acid. The elements that are key of an amino acid are carbon‚ hydrogen‚ oxygen‚ and nitrogen. There are about 500 different kinds of amino acids found but we recognize 23 of the amino acids that are known‚ they are classified into three groups‚ essential semi-essential‚ and non-essential. Each amino acid has unique characteristics

Global Warming and Acid Rain INTRODUCTION The phrase Global Warming has become familiar to many people as one of the important environmental issues of our day. Many views have been expressed concerning it‚ from the doom-laden to the dismissive. There is little debate that the earth is undoubtedly warming. It has been the subject of intense debate for decades now. Greenhouse gases such as carbon dioxide and industrial gases from fossil fuels play a huge role in why our environment is changing
