V. Questions 1. Correlate the number of carbon in the R group with the solubility of the acid in water.

NaHCO3(s) + HC2H3O2(aq) =CO2(g)+H2O(l)+NaC2H3O2(aq) Is this an oxidation or reduction reaction? Just choose one, not both.

5. Synthesis of aspirin a. Write the sequence of reactions to produce aspirin using salicylic acid, acetic anhydrous, and phosphoric acid.

What is the [H3O*1 in a 175 ml sample of 0.0629 M KOH(aq)? 9.08 x 10-13 mol L-1 O8.17 x 10-14 mol L-1 O1.59 x 10-13 mol L-1 O 2.78 x 18-14 mol L-1 6.08 x 10-13 mol L-1

What is the balanced equation for salicylic acid + acetic anhydride --> acetylsalicylic acid (aspirin) + acetic acid? When added, why is concentrated sulfuric acid a catalyst?

When setting up an organic reaction for the first time, a concentration of reactants in tens to hundreds of micromolar range (mM) is often required. How much solvent (DCM) is required to prepare a solution that has a reactant concentration of 200mM? a) 0.126mL b) 1.26mL c) 12.60mL d) 126mL e) None of the options is correct.

Q6

Can you please tell me what's the classify reaction for NaOH(aq)+HCI(aq). I've attached two images here. The one is for the record data and the other one is the test tube where we have to look for the reaction and then record data in our lab.
