Cite this document ... % Acid = (Massa(g/L)∙100)/1000g/L; % acetic acid = (45g/L∙100)/1000g/L = 4.5 % Conclusion/Discussion: Titration is a powerful method used in analytical chemistry to estimate the concentration of any solution. This caused the value, of the number of moles of HCl needed to neutralize NaOH, to be more accurate. Curcumin is yellow in acidic and dark yellow in basic solution, but if strong base, it become dark brown.And, because the pH range of curcumic is >7 (more than 7), it’ll base indicator, and it can used as indicator of titration, and with it, we can determine the equivalent point when the end point finally reached. The point of chemical equivalence is indicated by a chemical indicator or an instrumental measurement. How does titration determine concentration? The mole ratio and volume relates the concentration of the solutions. We hypothesized that the upper level dormitories would have lower concentrations of these divalent ions because seeing as how they are both heavy metals, they would tend to settle out of solution ... "Good news: you can turn to other's writing help. you A titration is the controlled addition of a solution of known concentration (the titrant) in order to determine the concentration of a solution of an unknown concentration.
