This study explores the concentrations and interactions of sodium chloride (NaCl) and glucose (Cglu) in various aqueous solutions. Multiple titration methods are employed to determine the molarity of NaCl and glucose across different volumes and conditions. Emphasis is placed on the effects of additional components, including water and other solutes. The findings aim to provide insights into the relationships between concentration, volume, and molarity, relevant for applications in biochemistry and medicinal chemistry.
