Carbon dioxide is acidic in nature and KOH is a strong base. Thus, carbon dioxide reacts with the potassium hydroxide by acid-base reaction and form a salt known as potassium carbonate and water as a by-product.

KOH+CO_{2}\rightarrow K_{2}CO_{3}+H_{2}O

Thus, due to the increase in KOH the mass of U-tube is also increases. This increased mass of the tube gives the mass of carbon dioxide produced. From its mass, the % of carbon in the Organic compound can be estimated.
