Acid-Base Titrations February 21‚ 2013 Abstract: With the given volume measurement of KHP and NaOH‚ the students experimented to calculate the mass of unknown acid and its equivalence point using a method called titration and titration curve. The known volume of an acid solution would be titrated by slowly adding drops of solution into NaOH‚ and the volume of base needed to react with the acid is measured throughout. By using those data‚ the students are able to find what they

Exercise 6: Acid-Base Titrations Nick Redmond Partner: Stephan Villavicencio Thurs. Section Lab date: March 19‚ 1998 Report date: April 6‚ 1998 Abstract: The equilibrium between acids and bases during a titration can be used to determine several characteristics of the acid or the base. Sodium hydroxide was standardized to 0.1035 M in three acid-base titrations of potassium hydrogen phthalate (KHP). This standardized NaOH solution was then used in a series of other titrations with acids

Acids and Bases are two groups of chemical compounds that generally have opposite characteristics. They have there own unique traits‚ acids taste sour‚ turn litmus red while bases taste bitter and turn litmus blue. The term pH relates to measuring the acidity or alkalinity of a solution‚ such as vinegar‚ or even a damp substance like soul. The neutral pH is 7‚ which is essentially water‚ with lower numbers indicating acidity and higher numbers indicating alkalinity. Hydronium ions (H3O+) are

everyone associates with acids and bases is the litmus paper‚ which has the ability to change the color in response to an acid or a base. Phenolphthalein is another common indicator use by beginners in chemistry because its color change is very obvious‚ making it easy to use. There are many other indicators that change color at different pH levels‚ and so are useful for different purposes. Many pigments found in nature can be quite effectively used as acid-base indicators. The purple eggplant peel
