Question

how would the equilibrium change if the ocean became more acidic? more h₂co₃ is made more hco₃⁻ is made

Explanation:

Step1: Recall Le - Chatelier's principle

When a system at equilibrium is subjected to a change, the equilibrium shifts to counter - act the change.

Step2: Understand the effect of acidity

An increase in acidity means an increase in $H^+$ concentration.

Step3: Analyze the equilibrium shift

The equilibrium is $H_2CO_3(aq)
ightleftharpoons H^+(aq)+HCO_3^-(aq)$. When $H^+$ concentration increases, according to Le - Chatelier's principle, the equilibrium shifts to the left to consume the added $H^+$. So more $H_2CO_3$ is made.

Answer:

More $H_2CO_3$ is made
