Description of Procedure: 2.00 g of sodium benzoate was dissolved in 10.0 mL of H2O. 7.0 mL of HCl was added to the solution and a pH of 2 (similar to stomach acid) was reached. Upon addition of the HCl‚ a white

Acid-base titrations can be conducted using the above samples against standardized aqueous NaOH and standardized aqueous HCl solutions respectively. 2. Introduction: Acetic acid‚ commonly known as ethanoic acid CH3COOH‚ is found in commercial vinegar. It is a weak organic acid that gives vinegar its characteristic pungent smell‚ sour taste and slight acidity. Being an

The aim of this experiment is to investigate the ranges at which three different buffer systems: Acetic acid/NaOH‚ Tris/HCl and Gylcine/NaOH are effective. Materials and Methods Three titrations were carried out: Acetic acid/NaOH‚ Tris/HCl and Gylcine/NaOH. 25ml of the weak acid or weak base was put into a beaker and its pH measured. Then it was titrated with the strong acid or strong base respectively while measuring the pH

Not only is the Taj Muhal suffering‚ but also other historic landmarks across the world. This is a metathesis (Double Replacement) reaction where (CaSO4”s”) is a produced as cations(+) and anions(-) exchange partners and pair such as the following: CaCO3+H2SO4 CaSO4+ H20+CO2.

Title Soda Ash: Great for the economy but detrimental to the body; So why is it involved in everyday life? Abstract Sodium carbonate‚ Na₂CO₃‚ commonly known as soda ash is used in the manufacturing of many economically important products such as the manufacturing of glass‚ chemicals‚ paper and detergents. Since sodium carbonate has a strong base‚ it is commonly used to neutralize acidic effects. Soda ash has a high pH in concentrated solutions and can irritate the eyes and skin as well

analyte was the soda ash sample and the titrant was the HCl which was standardized by a primary standard of known purity‚ the sodium carbonate. Standardization is the process in which the concentration of solution is accurately determined. A sample of sodium carbonate with 99.9% purity was dissolved in boiled water and titrated with HCl. Then‚ a sample of soda ash was dissolved in boiled water and then‚ titrated. In a this reaction of HCl with carbonate‚ the following reactions will take place:
