Determine whether aqueous solutions of the following salts are acidic, basic, or neutral: Al(OH)3 is a weak base, HNO3 is a strong acid, RbOH is a strong base, HI is a strong acid, KOH is a strong base, H2CO2 is a weak acid, CH3NH3OH is a weak base, HBr is a strong acid.
Suppose that you titrate a 3 g sample of orange juice and it turns out to contain only 95.5mg of vitamin C. Further, it took 32.45mL of DCP solution to reach the end point of the titration.
Problem- I want to make cis-2-pentene given propyne and other reagents as needed. I need to use retrosynthesis to get from my starting material (propyne) to my target material (cis-2-pentene).
A .400 M formic acid (HCOOH) solution freezes at -0.756 degrees C. Compute the Ka of the acid at that temperature. Presume that molarity is equal to molality. Do calculations to three significant figures and roud off to two for Ka.)
