pH is a scale used to measure the acidity or
alkalinity of an aqueous solution. It can be used to calculate the amount of
hydronium ions in the solution. It is expressed as the negative logarithm to
the base 10 of the concentration.

<span>pH= -log [4.5 x 10^-3]</span>
pH = 2.35
Answer:
as the products of that reaction
