Enter your answer in the provided box. an industrial chemist studying bleaching and sterilizing prepares a hypochlorite buffer using 0.450 m hclo and 0.450 m naclo. (ka for hclo = 2.9 × 10−8) find the ph of 1.00 l of the solution after 0.040 mol of naoh has been added.

Explanation:

1. pH of original buffer

(a) Calculate pKₐ

(b) Calculate the pH

We can use the Henderson-Hasselbalch equation to get the pH.

2. pH after adding strong base

(a) Find new composition of the buffer

The base reacts with the HA and forms A⁻

                 HA     +     OH⁻    ⟶     A⁻ + H₂O

I/mmol:    450            40              450

C/mmol:    -40           -40                 40

E/mmol:    410               0              490

(b) Find the new pH  

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
