Question

Answer 1

Answer #1

a)

pH = -log[H₃O⁺]

Therefore,

[H₃O⁺] = 10^-pH

[H₃O⁺] = 10^-7.5 = 3.16 x 10^-8 M

Concentration of Hydronium ions in milk = 3.16 x 10^-8 M

b)

pOH = 14-pH = 14-7.5 = 6.5

pOH = -log[OH^-]

[OH^-] = 10^-pOH = 10^-6.5 = 3.16 x 10^-7

Concentration of Hydroxide ions in milk = 3.16 x 10^-8 M

c)

pOH = 14-pH = 14-7.5 = 6.5

pOH value of milk = 6.5

Typically the concentration of hydronium, H3O+, or hydroxide, OH−, ions in an aqueous solution is less than 1 M. It is not uncommon to have hydronium ion concentrations that are much smaller, such as 2.60×10−5. pH, therefore, is a convenient way to restate the hydronium concentration. pH is equal to the negative log of a hydronium ion concentration in solution: pH=−log[H3O+] Access the pH calculation simulation, which will open in a new window. Edit the concentration by typing a value...
