# Problem: Determine the pH of each solution.a solution that is 4.7×10−2 M in HClO4 and 5.1×10−2 M in HCl

###### FREE Expert Solution

We are asked to calculate the pH of the solution with 4.7×10−2 M in HClO4 and 5.1×10−2 M in HCl.

The pH of a compound determines its acidity.

pH

▪ pH stands for the negative logarithmic function of hydronium ion concentration
can be calculated using the following equation:

Strong acids are considered strong electrolytes. They completely dissociate into ions when dissolved in water.

Strong binary acids – paired with a highly electronegative atom

Strong binary acids are:              HCl, HBr, and HI

Strong oxyacids (or oxoacids) - have 2 or more oxygens than hydrogens

Oxyacids → possess H+ ion, connected to nonmetal and oxygen

Common strong oxyacids are:                  HNO3, HClO3, HClO4, H2SO4

Exceptions to the rule are:                            Oxalic acid (H2C2O4) and Iodic acid (HIO3)

▪ both have 2 more O than H but are weak acids because carbon and iodine have low electronegativity
