Explanation:
= frequency of the tone = 329.6 Hz
= Time period of the sound wave
we know that, Time period and frequency are related as
= speed of the sound in the air = 341 ms⁻¹
wavelength of the sound is given as
= speed of the sound in the water = 1480 ms⁻¹
wavelength of the sound in water is given as
Answer:
The concentration of hydrogen ion at pH is equal to 2 :
The concentration of hydrogen ion at pH is equal to 6 :
There are 0.009999 more moles of ions in a solution at a pH = 2 than in a solution at a pH = 6.
Explanation:
The pH of the solution is the negative logarithm of hydrogen ion concentration in an aqueous solution.
The hydrogen ion concentration at pH is equal to 2 = [H^+]
The hydrogen ion concentration at pH is equal to 6 = [H^+]
Concentration of hydrogen ion at pH is equal to 2 =
Concentration of hydrogen ion at pH is equal to 6 =
The difference between hydrogen ion concentration at pH 2 and pH 6 :
Moles of hydrogen ion in 0.009999 mol/L solution :
There are 0.009999 more moles of ions in a solution at a pH = 2 than in a solution at a pH = 6.
