Aim: To investigate the rate of reaction between Calcium Carbonate and Hydrochloric Acid. Just from looking at the aim of the investigation I already know that a salt would be formed because a carbonate with an acid forms a salt. In this investigation the substance that is formed is Calcium Chloride‚ Water and Carbon Dioxide. The symbol equation for this is: CaCo3  Ca2+ + Co32- Hcl  H+ + Cl- Add these all together to get CaCO3(s) + 2H+(aq) --> Ca++(aq) + H2O + CO2(g) The rate of

THE EFFECT OF HYDROGEN BONDING ON RESISTING FLOW Design Investigating a factor affecting the viscosity of a mixture of liquid Research Question The effect of hydrogen bonding on resisting flow of five different liquids Background Theory Viscosity is the resistance of a fluid to flow‚ either within itself‚ or to moving past an objects moving through it. A liquid with high viscosity is thick and flows slowly. A liquid with a low viscosity is thin and flows quickly. Different liquids

concentrations. Scientific Background: Vinegar is an acid and there fore can be neutralised by an alkali. Acid + Alkali à salt + water Hydrochloric acid + Sodium Hydroxide à Sodium chloride + water Vinegar is a weak acid and therefore it only partially ionises in solution. CH3COOH ßà CH3COO- + H+ An alkali such as Sodium Hydroxide has a formula NaOH. If the alkali is strong then it ionises fully in solution. NaOH ßà Na+ + OH- When the acid H+ reacts with the alkali OH- the

zirconium tetrachlorohydrex gly can cause irritation in sensitive underarm areas. These irritations can cause allergic reactions like contact dermatitis‚ acne‚ or itching. The contact solution I use each morning includes Sodium Borate (Na2[B4O5(OH)4]·8H2O). According to my research‚ Sodium Borate is normally slightly irritating to skin and eyes. When chronic exposure occurs‚ it produce eye irritation‚ cough‚ and skin rash. The hairspray I use each morning includes Aminomethyl Propanol (C4H11NO). At higher

6 did not. Not many fruits and vegetables contain preservatives simply because they come from nature. One of the items contained Sodium Benzoate‚ a small percentage of people are extremely sensitive to sodium benzoate and can experience asthmatic attacks and other allergic reactions when they take in the preservative. A more normal problem is the combination of sodium benzoate and citric acid and ascorbic acid. When these ingredients mix‚ they form benzene‚ a cancer-causing chemical linked with leukemia

Preparation of Sodium Chloride through titration Abstract: acid-base titration is a technique commonly used to determine the moles of acid in a sample by adding a known volume of strong base of a known concentration. The strong base provides the hydroxide ion‚ to react quantitatively with the acid. The point at which the acid is completely and exactly consumed the known quantity of base is called the equivalence end point and is signalled by a colour change in the solution (end point). This colour
