Gastric juices have a ph of 1 or 2. this would indicate which of the following? -neutral fluids, perfect for decomposition reactions-numerous h+ ions and a low ph-numerous oh- ions and a high ph-numerous oh- ions and a low ph

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.

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

(note: if you don’t know what ⇌ means, read below: -

⇌(double head arrow) means reversible reaction).
