Calculate the pH if the [H]=0.000001

pH is 6

Explanation:

Given that,

pOH of solution = ?

[H+] of solution = 0.000001M

Recall that pH is the negative logarithm of hydrogen ion concentration in the solution. It is mathematically expressed as:

pH = -log(H+) where H+ is the concentration of hydrogen ion.

So, pH = -log(H+)

pH = - log (0.000001)

pH = - (-6)

pH = 6 [The two minus signs cancelled out]

Note that pH value of 6 is mildly acidic because any pH value less than 7 is said to be acidic

Thus, if the [H]=0.000001 the pH is 6

answer : (a) volume of the gas = 8.67 ×   l

                (b) second virial coefficient b = -1.21226 l/mole

solution :   given,     t = 300k

                                p = 20atm

                                z = 0.86

                                n = 8.2 mmoles = 8.2 × moles

                                r =   0.082 l atm/k/mol

        find,     (a) volume of gas   and (b) second virial coefficient b at 300k.

formula used :            

                          and            

(a)            

                    = \times 0.082\times 300}{20}[/tex]

                    = 8.67 ×   l

(b)      

                    = (0.00867-1) × 8.659

                    = - 8.5839 l/mole
