Ph And Temperature

The initial concentration of

%5Ctext%7BH%7D%5E%2B

ions in the solution is determined by the pH, which is 5. Thus, the concentration of

%5Ctext%7BH%7D%5E%2B

ions is:

%5B%5Ctext%7BH%7D%5E%2B%5D%20%3D%2010%5E%7B-5%7D%20%5C%2C%20%5Ctext%7BM%7D

After dilution, the new volume is 1 L, and the new concentration of

%5Ctext%7BH%7D%5E%2B

ions becomes:

%5B%5Ctext%7BH%7D%5E%2B%5D_%7B%5Ctext%7Bnew%7D%7D%20%3D%20%5Cfrac%7B10%5E%7B-5%7D%20%5C%2C%20%5Ctext%7BM%7D%20%5Ctimes%201%20%5C%2C%20%5Ctext%7Bml%7D%7D%7B1000%20%5C%2C%20%5Ctext%7Bml%7D%7D%20%3D%2010%5E%7B-8%7D%20%5C%2C%20%5Ctext%7BM%7D

The pH of the resulting solution is:

%5Ctext%7BpH%7D%20%3D%20-%5Clog(10%5E%7B-8%7D)%20%3D%208

Thus, the resulting pH is approximately 6.02.
