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

Task 4 – The Maintenance of the Acid – Base balance in the body (D1) pH is measured based on its acidity and alkalinity. There are many substances around the body that have different pH values. A pH of 7 is usually considered neutral‚ neither acid nor alkaline‚ this is the pH of water. In the body the acids and bases need to be in very close balance‚ this is called ‘acid base homeostasis. If it goes off too far in either direction then it could be fatal to the body. For example in the body the blood

Purpose of this experiment: The purpose of this experiment is to observe the neutralization reaction that occurs between strong acid and strong base solutions. The technique of titration is used to observe the acid content of the fluid in a car battery. 3. Procedure: Calculate the volume of 6.00 M NaoH that is needed

of an unknown solution of Sodium Hydroxide (NaOH) by titrating it with Hydrochloric Acid (HCl) and to identify any possible sources of error. A colour change from pink to yellow signified the end of each individual titre as the NaOH had been neutralised. Experimental: Method: Firstly two solutions were prepared to show the colour of the Phenol Red indicator in acid and alkaline conditions. These colours were then used to determine the end point of each titre. In the experiment 0.100M HCl (acid) was

Acid-base homeostasis is a complex synergy that involving lungs‚ kidneys and a buffer chemical in blood and blood cells. BACKGROUND A substance that has high concentration of hydrogen ion in solution is called acid and solution that has low concentration of hydrogen ion is base. Base
