**Calculating pH at the Equivalence Point**

**Problem Statement:**
Calculate the pH at the equivalence point for the titration of 0.22 M HCN with 0.22 M NaOH. Given that \( K_a = 4.9 \times 10^{-10} \) for HCN.

**Options:**

1. 10.98
2. 10.78
3. 10.58
4. None of the above
5. 11.18

**Note:** This is a multiple-choice question. To solve this problem, consider that at the equivalence point of a titration involving a weak acid (HCN) and a strong base (NaOH), the resulting solution is basic. Calculate using the expression for the \([OH^-]\) concentration and the \( K_w\) relation, where \( K_w = 1.0 \times 10^{-14} \).

**Multiple Choice**

- ( ) 10.98
- ( ) 10.78
- ( ) 10.58

Volumetric pipets are calibrated in a manner that takes into account the solution which remains at the tip. True Using the pipettor, you should turn the wheel on the pipette, draw up the solution until the meniscus is several centimeters above the calibration line, then quickly remove the pipette and put your thumb over the open hole of the pipet.
