Just 3 and 4. The stoichiometric ratio came to be 1:2. How would i write a balance equation and know if it is diprotic or triprotic DATE LAB TEAM MEMBERS Mole Ratio Study POST-LABORATORY QUESTION TA: 1. Determine the whole number mole ratio of moles of NaOH to your assigned acid and that of colleague. Using Mircosoft Excel, or any other data processing software, plot the temperature change vs. volume of sodium hydroxide data. Attach the two graphs to the lab report. (6 pts) and %. 2. Identify the limiting reactant in each trial for your assigned unknown acid only? (6 pts) 2 Trial 1 Trial 2 unLnA Trial 3 uhleno2n Trial Lynhnasn Trail 5 Trial 6,-nhat- Trial 7 ou Base on the stoichiometric ratio obtained from the graph, Write a balanced chemical equations for the reaction between the unknown acids and sodium hydroxide. (2 pts) 3. 4. Is your unknown acid monoprotic, diprotic, or triprotic? Explain your answer. (3 pts) Unknown code Unknown identity ult deto obtained from your colleagues determine whether the other twoExplanation / Answer
Unknown acid
3. Since the mole ratio came out to be 1 : 2
Balanced chemical equation becomes,
H2A + 2NaOH <==> Na2A + 2H2O
wherein H2A is the unknown acid
4. The acid consumed 2 moles of NaOH for the reaction (mole ratio 1 : 2) therefore, the unknown acid is a diprotic acid. 1 mole of NaOH consumed for each proton. Some possibilities for the diprotic acid would be H2CO3, H2C2O4, etc.
