Question two
A buffer solution is able to maintain a constant pH when small amounts of acid or base are added to the buffer. Consider what happens when 1 mL of a 5 M solution is added or 0.005 mol of HCl are added to a 100.0 ml solution acetic acid buffer that contains 0.0100 mol of Acetic acid, HC,H,O,, and 0.0100 mol of sodium acetate, NaC,H,O2. The initial concentration of both the acid and the base are 0.0100 mol/0.1000...

The best explanation for the shape of the graph below is: Substrate concentration The rate of reaction increases until all the active sites are full and the reaction reaches a maximum rate. The rate of reaction increases until some active sites remain empty and the reaction reaches a maximum rate The rate of reaction increases until the concentration of hydrogen ions exceeds the optimum and the tertiary structure is destroyed. The rate of reaction increases until pH becomes a limiting...

The graph below shows an enzyme- controlled reaction. The enzyme concentration is kept constant. At concentrations of substrate greater than X, which of the following statements is true? Rate of reaction 0 Concentration of substrate X The rate of reaction is limited by enzyme concentration. The rate of reaction tends towards zero. The substrate has an inhibitory effect. The products have an inhibitory effect.

When dealing with buffer systems, we often use the acid reaction to determine the equilibrium and set up the ICE table. The most common experimental method used to study acid-base systems is titration, which studies the stoichiometric addition of the acid to a base solution or the base to an acid solution to determine the value of K, or K, The value of the pK, or pK, is essential to the understanding of the buffer system, where pK, = -log...
