of NaOH‚ was placed in another burette. 25 mL of KHP was placed into the Erlenmeyer flask‚ which was also recorded as the volume of acid in the flask. A total of 19 mL of base‚ NaOH‚ was required for the endpoint‚ which was indicated by a very pale pink color. To calculate the molarity of NaOH‚ the following equation was used MNaOH x VNaOH = MKHP x VKHP therefore the molarity was .125 M.

the Unknown I. The pH value was 11 for the Unknown II. Then‚ we had to add phenolphthalein solution to the Unknowns. When we added it to the Unknown I‚ it turned cloudy and looked kind of milky. It didn’t turn pink because it was an acid. When we added it to the Unknown II‚ it turned bright pink. This indicated that it was a base. Next‚ we had to add a piece of magnesium ribbon to the Unknowns. When we added it to the Unknown I‚ a hydrogen gas and salt was produced. It was an exothermic reaction because

For my summer reading project I chose Melody. For this project we had to pick three symbols for our poster. The three symbols I included were a Mello Yello can‚ the cerebral palsy symbol‚ and a brain. I chose a Mello Yello can because that was Melody’s favorite drink. She loved it so much that she was nicknamed “Mello Yello”. In the book it stated “Mello Yello was my favorite. Mrs. V even started calling me that.” (Draper‚ pg. 44). This was important because she loved being called this. I placed
