Jacob Hernandez October 23‚ 2014 Hima Lahari Marneni CHEM 1411. 114 Post Lab Report 6 Introduction The purpose of this lab is to determine the concentration of HCl when titrated with a standardized NaOH solution‚ through means of the titration method. My hypothesis is When an unknown concentration of HCl is titrated with a known volume of standardized NaOH solution‚ one can gather enough data to determine the concentration of the unknown (HCl). My prediction is If an unknown concentration of HCl

Observations: When Malaria is present and infects red blood cells‚ parasites can infect cells carrying defective hemoglobin which may result in death. Allele frequency changes over time depending on the pressures or circumstances facing a particular population. African populations are especially impacted by both malaria and sickle cell anemia. Depending on the impacted population‚ allele frequency often shifts and well suited organisms are likely to survive and allele frequencies can increase
