TITRATION CALCULATION EXAM QUESTIONS & ANSWERS

TITRATION CALCULATION EXAM QUESTIONS & ANSWERS What are the purpose of the coefficients on balanced equations - ANS-- To balance equations - And to also use them to find the mole ratio of the unknown solution's amount Steps to volume-volume stoichiometry - ANS-- Make an equation between the two solutions involved with the reaction, balance them. - Based on the question, identify the solution with an unknown variable ---> on the reactants side, find the coefficient of the unknown solution and divide it over the coefficient of the known solution---> this is the mole ratio - Find the amount of moles of the known substance and multiply that by the mole ratio to find the amount of moles of the unknown solution. - Perform inverse operations to find either the volume or concentration of the solution Steps to calculating the unknown concentration of an unknown solution - ANS-- Perform the same steps as volume- volume stoichiometry Steps to calculating the concentration of a diluted unknown solution - ANS--
