### Tartaric Acid IonizationTartaric acid is found in many fruits, including grapes, and is partly responsible for the dry texture of certain wines. As a diprotic acid, it has two dissociation constants, \( K_{\text{a1}} = 1.00 \times 10^{-3} \) and \( K_{\text{a2}} = 4.60 \times 10^{-5} \).**a. Write the equation for the 1st ionization of tartaric acid.**\[ \text{H}_2\text{C}_4\text{H}_4\text{O}_6 (aq) \rightleftharpoons \text{H}^+ (aq) + \text{HC}_4\text{H}_4\text{O}_6^- (aq) \]**b. Write the equation for the 2nd ionization of tartaric acid.**\[ \text{HC}_4\text{H}_4\text{O}_6^- (aq) \rightleftharpoons \text{H}^+ (aq) + \text{C}_4\text{H}_4\text{O}_6^{2-} (aq) \]**c. Write the \( K_a \) expression for the 1st ionization.**\[ K_{\text{a1}} = \frac{[\text{H}^+][\text{HC}_4\text{H}_4\text{O}_6^-]}{[\text{H}_2\text{C}_4\text{H}_4\text{O}_6]} \]**d. Write the \( K_a \) expression for the 2nd ionization.**\[ K_{\text{a2}} = \frac{[\text{H}^+][\text{C}_4\text{H}_4\text{O}_6^{2-}]}{[\text{HC}_4\text{H}_4\text{O}_6^-]} \]**e. What is the equilibrium concentration of the reactants and products from the 1st ionization of a 0.250 M solution of tartaric acid?**To solve, use the initial concentration and the \( K_a \) expression for the 1st ionization
