A buffer solution is made from lactic acid (pKa = 3.86) and sodium lactate. At a pH of 2, which is true?

[HC 3 H 5 O 3 ] > [NaC 3 H 5 O 3 ]

[HC 3 H 5 O 3 ] ~= [NaC 3 H 5 O 3 ]

[HC 3 H 5 O 3 ] < [NaC 3 H 5 O 3 ]

A buffer solution is made from lactic acid (pKa = 3.86) and sodium lactate. At a pH of 4, which is true?

[HC 3 H 5 O 3 ] ~= [NaC 3 H 5 O 3 ]

[HC 3 H 5 O 3 ] > [NaC 3 H 5 O 3 ]

[HC 3 H 5 O 3 ] < [NaC 3 H 5 O 3 ]

A buffer solution is made from lactic acid (pKa = 3.86) and sodium lactate. At a pH of 7, which is true?

[HC 3 H 5 O 3 ] < [NaC 3 H 5 O 3 ]

[HC 3 H 5 O 3 ] > [NaC 3 H 5 O 3 ]

[HC 3 H 5 O 3 ] ~= [NaC 3 H 5 O 3 ]

A buffer solution is made from equal concetrations of lactic acid and sodium lactate. When NaOH is added to the buffer, which is true

[HC 3 H 5 O 3 ] < [NaC 3 H 5 O 3 ]

[HC 3 H 5 O 3 ] > [NaC 3 H 5 O 3 ]

[HC 3 H 5 O 3 ] ~= [NaC 3 H 5 O 3 ]

Both [HC 3 H 5 O 3 ] and [NaC 3 H 5 O 3 ] increase

Both [HC 3 H 5 O 3 ] and [NaC 3 H 5 O 3 ] decrease

A buffer solution is made from equal concetrations of lactic acid and sodium lactate. When HCl is added to the buffer, which is true

[HC 3 H 5 O 3 ] > [NaC 3 H 5 O 3 ]

[HC 3 H 5 O 3 ] ~= [NaC 3 H 5 O 3 ]

[HC 3 H 5 O 3 ] < [NaC 3 H 5 O 3 ]

Both [HC 3 H 5 O 3 ] and [NaC 3 H 5 O 3 ] increase

Both [HC 3 H 5 O 3 ] and [NaC 3 H 5 O 3 ] decrease
