was conducted in order to determine the chemical composition of an unknown organic acid. A known mass of acid was dissolved into 30mL of either water or methanol (depending on solubility) and titrated with standardized sodium hydroxide. Data from this allowed the molar mass of the acid to be calculated if it was either monoprotic or diprotic. Titration Table: |Trail |Acid Used (mg) |Concentration of base |Volume of base (mL)

Lime scale form when hot water is heated about 61’C. All the acids listed about remove lime scale because the ions in the acids react with the calcium ions in limescale to then form a soluble salt. The acids also react with the carbonates in lime scale to produce water and carbon dioxide. Then the whole solution washes out taking away as much lime scale and possible. Sulfamic acid The advantages of using sulfamic acid as a de-scaler are that it is the faster de-scaler which means it can give

Sandeep Voleti- Period 4/5 Honors Chemistry Titration Lab Writeup Introduction Titration is a method‚ which is meant to find the concentration of either an acid or a base by adding a measured amount of it to a known volume and concentration of an acid or base1. Titration starts with a beaker or Erlenmeyer flask containing a very precise volume of the known concentration solution and a small amount of indicator‚ which is put underneath a burette containing the solution with unknown concentration1

CITRIC ACID IN A SOFT DRINK USING ACID/BASE TITRATION Copyright: Department of Chemistry‚ University of Idaho‚ Moscow‚ ID 83844-2343; 2007. INTRODUCTION The acid content of many foods and beverages contributes significantly to their taste. Soft drinks often contain varying quantities of several acids‚ which give sodas their tart flavor. In cola products‚ these acids are predominantly carbonic acid (from the carbonated water) and phosphoric acid. In sodas such as Squirt and 7-Up‚ the acids are

Alondra Garcia Mr. Deegan Pre-Ap Chemistry-1 22 February 2013 Pink and Bubbly Research: Phenolphthalein is an acid/base indicator which expresses the properties of an element. It is colorless when it is an acid and pink when it is a base. Ammonium is familiar base‚ used for cleaning oils and grease from any types of surfaces. Ammonium is a fairly strong base with a pH of 11 and will dissociate completely into an aqueous solution (water). Water is universal and has a neutral base with a

neutralisation reaction is an exothermic chemical reaction involving proton transfer‚ where an acid and a base interact to form a salt and sometimes water. Employing this concept‚ neutralization reactions may be used in laboratories to clean up accidental acid and base spills on workbenches of flooring. But because of the exothermic nature of the neutralisation process‚ we should never use strong acids or bases in cleaning up spills as excess employment of these substances‚ where itself is caustic

addition of one solution to another until the reaction reaches neutralization‚ which is often indicated by color change. Acid-base titration is the most frequently used procedure to determine the concentration of an acid or basic solution. This titration is also called as neutralization reaction. By adding an indicator to the solution‚ we will able to detect when the reaction between acid and the base is complete. Soft drink is a beverage that is non-alcoholic‚ carbonated drinks that contains many ingredients

on the person but the statement. I think it is citric acid and baking soda. Eighth graders have to find out what a mystery mix is from an assortment of chemicals‚ by adding water and mixing them together. Some think it is citric acid and baking soda‚ and some still think it’s citric acid‚ baking soda‚ and Epsom salts. Then they looked at the mix dry and it looked too rectangle and rocky‚ then what the mystery mixture seemed to be. Citric acid is more circular than Epsom salt. But other people thought

ACIDS 1. Acids are chemicals which will turn litmus paper red. Litmus is a colored Chemical which can change from red to blue and back again. Which colour it is Depends upon the concentration of Hydrogen ions. If the concentration of Hydrogen ion is higher than it is in pure water then the litmus will turn red. If it is lower than in pure water the litmus will turn blue. 2. An acid is a substance that turns blue litmus paper red acids can‚ be identified due to specific
