Determination of KHP – Acid - Base Titration For determining purity of unknown KHP‚ acid – base titration was used. Molarity of titrant in this case NaOH was standardized as 0.04958(±0.00011) M. Purity of unknown KHP was calculated as 35.88(±0.16) %. • Introduction Acid – base titration is typical method of determining unknown figures. Acid – base titration means that by using neutralization between acid and base. Abrupt changing of pH says whether procedure is done or not. pH indicators

Right to self-determination All of us have the right to self-determination. In a far view‚ right of self-determination simply means that all people have the right to freely determine their political status and pursue their economic‚ social and cultural development. This merely involves the freedom to acquire and dispose of property and wealth generally as the person choses. Right to self-determination is an unalienable right; the government can’t take the right away. The specific right applies

Determination of pKa James McDuffie ABSTRACT: In this lab‚ the pKa of unknown solution #4 was measured Introduction: This lab focused on the equilibrium constant‚ Ka. Ka is associated with chemical properties of acids. The equivalence point will be reached once the moles of OH- equal the moles of HA and once this point is reached‚ the PH changes very quickly. With the results‚ a titration curve should be produced. Experimental Section Materials and Methods: A buret with NaOH solution

The Importance of Determination Everyday people face challenges‚ but it is important that one does not give up‚ and to keep trying until they successfully overcome the obstacles that stand in their way. “Mother to Son” by Langston Hughes and “Still I Rise” by Maya Angelou are two different works written by two different authors yet they both convey the same message. Together‚ the two authors stress the significance of pushing harder when faced with conflicts rather than simply giving up. Using

Lab #2 Determination of Density Britney Williams Chemistry 121 Dr. Yu 1/29/13 Purpose: To determine the densities of aluminum and zinc cylinders Density is the relationship between the mass of an object and its volume. Sometimes density can be easy to sense. If two objects have exactly the same shape and size‚ the denser one may feel heavier. If their densities are close together‚ it can be hard to tell the difference. It gets really tough if you are dealing with materials that have very different

Free will Vs Determination Do you make your own choices or your destiny has been decided for you by circumstances behind your control? For thousands of years‚ this question has puzzled philosophers‚ scientist and anyone who thinks about how they choose to act and live. Part of the complexity of the matter is related to the metaphysical nature of the subject which has a close affinity with the concept of GOD.
