Select the statements that correctly describe a buffer. a) An acid added to the buffer solution reacts with the weak base of the
Tom [10]

Answer:

  • <em>(B.) The pH of a buffer solution is determined by the ratio of the concentration of conjugate base to the concentration of strong acid.</em>
  • <em>(C.) A buffer is generally made up of a weak acid and its conjugate base. </em>
  • <em>(D.) The pH of a buffer solution does not change significantly when any amount of a strong acid is added.</em>

Explanation:

A buffer is  solution which resists change in pH upon addition of either acids or bases.

The pH of a buffer is calculated by the ratio of the concentration  of base to concentration of acid. The weak acid and conjugate base have a Ka similar to the pH desired.

If 1.0 gram of hydrogen reacts with 19.0 grams of fluorine, then what is the percent by mass of fluorine in the compound that is
astraxan [27]
The reaction between hydrogen (H2) and fluorine (F2) is given below,
                                   H2 + F2 ---> 2HF
One mole of both hydrogen and fluorine yields to 2 moles of hydrogen fluoride. This can also be expressed as, 2 grams of hydrogen and 38 grams of fluorine will form 40 grams of hydrogen fluoride. From the given, only 20 grams of HF is formed with 19 g of it being fluorine. Thus, the percentage fluorine of the compound formed is 95%.
