Ibuprofen is a nonsteroidal anti-inflammatory drug. Its molecular formula is C13H18O2 with a molecular structure shown below. Is a solution of Ibuprofen acidic, neutral or basic?

Consider an oxyacid with the formula HXO4. How does the acidity change with increasing electronegativity of X?
Encircle the weaker base between the two. Explain why.
HSe− or HS−
Identify whether H3PO4 is an Arrhenius acid or an Arrhenius base and write a chemical equation showing it is an acid or base.
Identify the strongest Lewis acid among the following: BCl3, BF3, BI3, BBr3.
Like all equilibrium constants, the value of Kw depends on temperature. At body temperature (37 °C), Kw = 2.4×10−14. What are the [H3O+] and pH of pure water at body temperature?
