Answer:
Gastric juices have a pH of 1 or 2. This would indicate numerous H+ ions and a low pH
Explanation:
Highers concentrations of [H⁺] means very low pH.
pH = - log [H⁺]
Imagine this two concentrations:
[H⁺]₁ = 0.2 M
[H⁺]₂ = 0.0006 M
[H⁺]₁ > [H⁺]₂
pH₁ = - log 0.2 → 0.70
pH₂ = - log 0.0006 → 3.22
Then pOH₁ = 14 - 0.70 = 13.30
pOH₂ = 14 - 3.22 = 10.78
[OH⁻]₁ = 10^-pOH = 5.01×10⁻¹⁴
[OH⁻]₂ = 10^-pOH = 1.66×10⁻¹¹
As pH is so low, [OH⁻] is more and more lower.
