BUFFER SOLUTION (ACID) An acidic buffer solution is simply one which has a pH less than 7. Acidic buffer solutions are commonly made from a weak acid and one of its salts - often a sodium salt. Objectives: 1. Measure the pH of the unknown solution first with indicators and then with pH paper. 2. compare the buffer solution with both a strong acid and a weak acid materials: 2 30 mL beakers 2 100mL volumetric flask 1 10mL pipet 2 aspirator 1 50mL graduated cylinder 1 10mL graduated

Guantanamo: past‚ present and future The Naval Base at Guantánamo Bay is the oldest U.S. military base still operating outside the U.S. It has been under U.S. control since 1898 but it was not used to hold prisoners from the Afghanistan war until January 2002. Since then‚ hundreds of “law combatants” have been held there against the Geneva Convention and their rights have been removed. Guantanamo Bay Detention Camp became a matter of international concern when it was stated that the prisoners

A buffer solution can maintains a narrow range of pH even when strong acid are added. In our experiment‚ we can see water is not a buffer‚ water can undergo very big changes when small amounts of strong acid or strong bases are added. When the strong acid‚ 100µl HCl was added into the dd water‚ the pH value changed from 7.38 to 5.83 which mean the dd water has turn into acid. The same phenomenon occurs while strong base‚ 100µl NaOH was added into the dd water. The pH value changed from 7.07 to 9

Getting Back on Track One of the things I have learned and got engaged in when I was in high school was sports. Thanks to the UB Science High School’s Youth Development Training (YDT) program‚ I have learned various sports and have excelled in some of them. While I was able to stay active until I got into college‚ I began to slow down when I started working. Though swimming and surfing were frequently on my agenda‚ they were only done for leisure. It came to a point wherein the closest
