A solution is prepared by dissolving 4.9g sucrose (C12H22O11) in 175G water. Compute the boiling point of this solution. Sucrose is anon electrolyte.
When the following reaction is balanced in basic solution using the lowest possible whole number coefficients, the coefficient of Cr(OH)3(s) will be: Cr(OH)3(s) + Cl2O7(aq) --> CrO42-(aq) + ClO2-(aq)
Really confused on calculating/finding the half-equivalence point in a titration curve. This was a lab experiment done in my chem lab. We added 0.0750 M NaOH to acetic acid (pipet 10.00mL of ~0.1M HCH3CO2 into the beaker and add 40mL of DI water).
