chemistry- acid base problems
When a hydronium ion concentration equals 1 x 10-10 moles per liter, what is the pH of the solufion? Is the solution acidic or basic?
The pH of this solution is 10, which is basic.
calculate the pH of [H3O+] = 1 ✕ 10-8 M
pH = 8
calculate the pH of [OH -] = 1 ✕ 10-1 M
pH = 13
Write the formula and name of the conjugate base for HNO2
[NO2]- nitrite
A strong acid is different from a weak acid because a strong acid.
is completely dissociated in water.
It produces H3O+ ions in water.
acid
is [H3O+] = 1.0 ✕ 10-5 M acidic basic or neutral?
acidic
is [OH -] = 1.0 ✕ 10-13 M acidic basic or neutral?
acidic
shampoo, pH 5.7
acidic
It turns litmus red.
acids
It is a proton (H+) acceptor.
base
It neutralizes bases.

drain cleaner, pH 11.2
basic
is [H3O+] = 1.0 ✕ 10-9 M acidic basic or neutral?

Write the formula and name of the conjugate base for HCO3-
carbonate, [CO3]2-
As the pH increases, the hydroxide ion concentration
gets larger.
As the hydronium ion concentration increases, the pH
goes down.
