involve the reaction of an acid and a base to produce a salt (ionic compound) and water. Acid + Base ( Salt + Water □ In this lab‚ sulfamic acid (a weak acid which contains one acidic hydrogen) will be used: H2NSO2OH(aq) + NaOH(aq) ( NaOSO2NH2(aq) + H2O(l) (Net Equation: H+(aq) + OH-(aq) ( H2O(l)) □ Titration is a process of neutralization □ Titration is commonly used to determine the concentration of an acid or base in a solution.

FORD Ka (B) Case: 1) After using the similarity data provided for the Ford Ka market research study to perform a MDS analysis on the whole sample‚ the map (exhibit 1) shows the position of the different cars relative to each other. We can see two groups: one of them made of Peugeot 106‚ Ford Fiesta and Opel Corsa (practical and safe cars)‚ the other one made of Nissan Micra and Fiat 500 (dull and outdated cars). The other cars cannot be grouped together but there are all the same similarities

Formic acid is known to be the simplest carboxylic acid‚ and it is an important factor in chemical synthesis and occurs naturally. The chemical formula for Formic Acid is CH202‚ and is mostly found in the venom of bee and ant stings. Formic acid is clear and colorless with a pungent odor. Formic acid is used in many ways; Formic acid is used to preserve livestock. It is also sprayed on animal food and fresh hay to reduce the decay rate. It can also be used as a pesticide to protect bee

Which leader would you rather have: One that is Morally Strong or Morally Weak? When asked the question‚ which leader would you want to have…one that is morally strong or morally weak‚ it makes you wonder what would be the best for the country. Someone that is morally weak doesn’t care about other people‚ just the best thing for him or her and in some instances that could be the best thing. They know what they want and they will never stop until they get it. Yet‚ sometimes the person can case

Name: Name of lab partner: Date: Title: Determination of the valency of magnesium Objective: To study the quantitative relationship between the amount of reactant and products of a reaction. A known starting mass of magnesium and the measured collection of hydrogen gas will be used to determine the reaction stoichiometry and the valency of magnesium. Introduction: In Chemistry‚ stoichiometry is the study of the quantitative relationship between amounts of reactants and products of a reaction

effect of citric and buffered lactic acids on the flavour of hard-boiled sweets and the effect of acids on various flavours in high temperature applications. Introduction Materials and Methods An amount of water‚ sugar and glucose syrup of 30g‚ 100g and 70g were weighed respectively into a stainless steel pot. The mixture was then heated and removed immediately from the induction cooker after reaching the desired temperature of 145˚C. Flavours of 0.51g and acid of 1.20g was added immediately afterwards

Chemistry Research Paper What is an anti acid? According to Cindy Quarters (2010)‚ “Antacids are medicines that are taken orally to help relieve sour stomach‚ heartburn‚ or acid indigestion”. This medicine is available without prescription but it is needed to take the correct dose. The different types of anti acids include calcium carbonate‚ sodium bicarbonate‚ magnesium hydroxide‚ aluminum hydroxide‚ and dihydroxyaluminum sodium carbonate. The cost of the anti acid will depend on how effective it is‚
