### Titration Problem

**Problem Statement:**

4) 35.0 ml of 0.50M HA (\(K_a = 7.0 \times 10^{-5}\)) is titrated with 0.25M NaOH. Calculate the pH at the endpoint.

**Explanation:**

- HA is a generic weak acid with a given acid dissociation constant (\(K_a\)).
- The titration involves neutralizing this acid with a sodium hydroxide (\(NaOH\)) solution.
- The endpoint of a titration is where the amount of titrant added is stoichiometrically equivalent to the amount of substance initially in solution.
- The task is to calculate the pH at this point.

**Note:**

No graphs or diagrams accompany this problem.

In our first lab experiment we will be identifying metals by measuring theirdensities and comparing them to known values. Here at NJIT we have a very large and generouslaboratory materials budget, so all sorts of exotic and extremely valuable metals will be providedfor the experiment. Using the values listed below, determine the identity of the metal samples.If the density value determined is not amongst the values below then one of those cheapRutgers samples crept into our stock of metal samples and you should answer “unknown metal”.Note: volume measurements are not very exact. If your density determination is off by 0.1 or0.2 from the known value, that’s probably good enough for an identity. Table in image 4a. You weigh your sample and determine it weighs 71.8 grams.
