Explanation:

Step1: Write the equation for the reaction that goes with \(K_{a1}\)

Ascorbic acid (\(H_2C_6H_6O_6\)) donates one proton (\(H^+\)) to water (\(H_2O\)). The reaction is \(H_2C_6H_6O_6+H_2O
ightleftharpoons H_3O^++HC_6H_6O_6^-\)

Step2: Write the equation for the reaction that goes with \(K_{a2}\)

The \(HC_6H_6O_6^-\) ion donates one proton (\(H^+\)) to water (\(H_2O\)). The reaction is \(HC_6H_6O_6^-+H_2O
ightleftharpoons H_3O^++C_6H_6O_6^{2 -}\)

Answer:

For \(K_{a1}\): \(H_2C_6H_6O_6+H_2O
ightleftharpoons H_3O^++HC_6H_6O_6^-\)
For \(K_{a2}\): \(HC_6H_6O_6^-+H_2O
ightleftharpoons H_3O^++C_6H_6O_6^{2 -}\)
