Question

Determining the Balanced Chemical Reaction Equation Which set of data do you trust more? Circle: Run Run 2 Average Based on your data, how many moles of NaOH react with I mole of succinic acid? (Rounded to nearest integer value.) The following is the reaction in word form: sodium hydroxide + succinic acid - water + sodium succinate Use your experimental ratio rounded to integer values of NaOH to Succinic acid to insert coefficients for just the reactants: 2 NaOH + L C.H.O. - "products" Succinic Acid is an acid, so it can be written in the "Acid form", with the acidic Hydrogens first. Ex. HCI, H,SO., HC H2O2 (acetic acid) or H.C.H.O. (succinic acid) Note: not all the 's are acidie! When NaOH reacts with an acid, an OH ion takes an H' from the acid. The products are HOH, Na'ion(s), and an anion of the acid, less one or more Based on your coefficients, how many NaOH were added for each C.HO? 2 Based on your coefficients, how many H were removed from each C.H.O.? Based on your experimental Show the removal of the hydrogen ion(s) by entering the coefficients and subscripts at the (1) below. H.C_H_O4 (aq) + H+ (aq) + CH 022 (aq) The anion is called "succinate". Write the formula of the ionic compound "sodium succinate" using the correct number of Nations to balance charge: Rewrite the equation including the products, and check the entire equation to see that it is balanced. For the Succinic Acid, write it in the "Acid form and write water as HOH to make balancing the equation easier. IF 20.0 grams of succinic acid reacted, how many grams of NaOH would be required?

confused on the rest of these problems

Answer 1

The equations can be written as follows.

i) 2 NaOH + C₄H₆O₄ ----> H₂O + Na₂C₄H₄O₄

The mole ratio NaOH:C₄H₆O₄ = 2:1

ii) H₂C₄H₄O₄(aq) <----> 2 H⁺(aq) + C₄H₄O₄^2-(aq)

Succinic acid is a diprotic weak acid.
