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

the equation that correctly represent the reaction for formation of ammonia is

n2+ 3h2 → 2nh3 (answer d)

1 mole of nitrogen gas (n2) react with 3 moles of hydrogen gas (h2) to form 2 moles of ammonia ( nh3). this is in a process known as haber process were iron is used as a catalyst and reaction take place that a higher temperature and pressure. the process is exothermic hence energy is released.
