pH scale is used to determine the acidity of a solution
pH is calculated using the H⁺ concentration
pOH scale is used to determine how basic a solution is
pOH is calculated using the OH⁻ concentration
pH and pOH are related in the following formula
pH + pOH = 14
pH = 3
pOH = 14 - 3
pOH = 11
pOH is calculated using the following formula
pOH = - log[OH⁻]
[OH⁻] = antilog(-pOH)
[OH⁻] = antilog(-11)
[OH⁻] = 1 x 10⁻¹¹ M
the [OH⁻] concentration of lemon juince is D) 1 x 10⁻¹¹ M
1 Cal ---------- 4.184 J
? Cal ---------- 130.0 J
130.0 x 1 / 4.184 => 31.07 Cal
