Why would the addition of alkali to this system lead to less CO2 (aq) being present?thank youu

Final answer: Adding alkali to a CO2-containing system decreases the concentration of CO2 (aq) because the hydroxide ions from the alkali react with CO2 to form bicarbonate ions, thereby shifting the equilibrium and reducing the amount of CO2(aq) present. Explanation: The addition of an alkali to a system containing CO2 (aq) leads to a decrease in the concentration of CO2 (aq) as the alkali reacts with CO2 to form bicarbonate (HCO3-). This reaction can be represented by the following equation: OH-(aq) + CO2(aq) → HCO3-(aq) When an alkali, which contains hydroxide ions (OH-), is added to the system, these hydroxide ions react with CO2 in the water to form bicarbonate ions. This results in a reduction of the aqueous CO2 concentration. Additionally, the system tries to maintain equilibrium by shifting to counterbalance the effect of the added alkali, thereby further reducing the concentration of CO2(aq). The CO2/HCO3- buffer system helps to maintain a constant pH, and the addition of alkali is usually compensated by the body or the environment to limit the change in pH. However, in a closed system, where replenishment of CO2 is not available, the reaction of alkali with CO2 would result in a definitive decrease in the concentration of CO2 (aq).

Answer: Why would the addition of alkali to this system lead to less CO2 (aq) being present? Because the alkali would neutralise the acid in the system. This would reduce the concentration of acid in the system. hope it helps you and have a nice day
