**Buffer Solution Analysis****Problem:**A 1 liter solution contains 0.587 M hydrocyanic acid and 0.440 M sodium cyanide. Addition of 0.220 moles of hydrobromic acid will:*(Assume that the volume does not change upon the addition of hydrobromic acid.)***Options:**- [ ] Not change the pH- [ ] Exceed the buffer capacity- [ ] Raise the pH by several units- [ ] Lower the pH by several units- [ ] Lower the pH slightly- [ ] Raise the pH slightly*(Select all that apply.)***Analysis:**This scenario involves the addition of a strong acid (hydrobromic acid) to a buffer solution containing a weak acid (hydrocyanic acid) and its conjugate base (sodium cyanide). The buffer is expected to resist changes in pH when the strong acid is added. However, if the amount of strong acid added exceeds the buffer capacity, a more significant pH change may occur.
