- MCG EXAM 1 QUESTIONS AND ANSWERS 
How does a buffer reduce the effect of added acid or base on the pH of a solution? - CORRECT 
ANSWERA buffer is able to resist pH change because it is able to dissociate into conjugate acid 
and conjugate base to neutralize other acids and bases added to the solution before they interact with 
water to change pH. These dissociated components are both present in appreciable 
amounts and exist in an equilibrium.

---8September 20252025/2026A+
- Electronegativity of water - ANSWERThe different electronegativities of hydrogen and oxygen make water a polar molecule capable of forming hydrogen bonds. This makes water a good solute. 
 
Hydrophobic interactions - ANSWERNon-polar hydrophobic compounds dissolve poorly in water. These compounds minimize their surface area exposed to water by forming aggregates in which the hydrophobic groups go to the interior through hydrophobic interactions. Only the more polar portions interact with water.
