up; sometimes it is easier to measure the change in the amount of product that has been produced. The reaction between metals and acids Acids and bases When acids react with bases‚ a salt and water are made: • acid + metal oxide → salt + water • acid + metal hydroxide → salt + water Remember that most bases do not dissolve in water. But if a base can dissolve in water‚ it is also called an alkali. Reactive metals Acids will react with reactive metals‚ such as magnesium and zinc‚ to make a

Acid Determination of Vitamin C Tablets and Salt Solutions Chem 1290-016 03-05-2010 ------------------------------------------------- Purpose: The purpose of this lab was to use acid-base titrations to find the mass percent of ascorbic acid in a Vitamin C tablet. A known concentration of sodium hydroxide was used and the value found was compared to the stated amount of ascorbic acid listed on the vitamin container. Also in this lab the acidity of different salt solutions were tested using

The pH level of foods is important to food microbiology because having proper pH levels can prevent food borne illness. This is of extreme importance when it comes to canning of foods in particular. Many home canned foods can be a breading ground

Determination of acetic acid in vinegar using acid-base titration 1. Scope The goal of this analytical procedure is to determine the acetic acid content of two samples of vinegar produced by Kolinska‚ Ljubljana‚ Slovenia. These samples are: Sample No. 1: vinegar made from wine‚ 4% Sample No. 2: vinegar made from alcohol‚ 9% The smallest quantity of the sample is 100 mL. Interesting results may be obtained by comparing the acidity of both samples of vinegar with factory analysis data. 2. Principle

Chem Final Write Up- Kool Aid Lab Total Acid This part of the lab requires titration of Kool Aid with an NaOH solution. The reason titrations are used is to determine the concentration of an unknown solution by reacting a strong acid with a strong base. Titrations are hard to accomplish‚ though‚ due to the fact that indicators used to show the endpoints are very sensitive and one drop could make the solution titrate past its endpoint. Blue stock solution: 3 mg/L Yellow stock solution: 35 mg/L

It is used in the manufacture of soap‚ glass‚ paper and as a source of alkalinity‚ that is‚ as a base. Glass‚ paper and as a source of alkalinity‚ that is‚ as a base. Soda ash‚ which is primarily sodium carbonate‚ contains unreacted sodium hydrogen carbonate and other impurities. The total acid neutralizing capacity of a soda ash sample‚ its alkalinity value‚ can be stated in terms

When an acid is dissolved in water‚ there are more hydrogen ions(H+) present than hydroxyl ions(OH-) due to the fact that acids donate hydrogen ions. An alkaline or basic solution accepts hydrogen

it can be titrated with a base. Titration is a method used in order to ascertain the amount of a constituent in a solution by measuring the volume of a known concentration of a reagent required to complete a reaction with it‚ typically using a burette. The equivalence point of a titration occurs when chemically equivalent amounts of acid and base are present. In this experiment‚ the equivalence point occurs when the moles of acid in the solution equals the moles of base added in the titration.
