You can refer to the attached graph which shows the amount of carbon produced from the antacid tablets.
The x-axis represents the number of tablets while the y-axis represents the amount of carbon dioxide produced.
Following the graph, we can find that:For four tablets of antacid, nearly 60 ml of carbon dioxide is produced.
Answer:
100mL of 0.10M HNO2 and 0.10M NaNO2
Explanation:
because solution has the greatest buffering capacity when the concentration of the weak acid is = at the concentration of its conjugate base.
I think the answer is c but I’m not for sure
an acid is an ionic compound that produces positive hydrogen ions when dissolved in water and a bacis is an ionic compound that produces negative hydroxide ions when dissolved in water
