### Identifying the Major Species in Weak Acid or Weak Base#### InstructionsThe preparations of two aqueous solutions are described in the table below. For each solution, write the chemical formulas of the major species present at equilibrium. You can leave out water itself.Write the chemical formulas of the species that will act as acids in the 'acids' row, the formulas of the species that will act as bases in the 'bases' row, and the formulas of the species that will act as neither acids nor bases in the 'other' row.Keep in mind that HCN is a weak acid.#### Table Description- **Solution 1:** 0.3 mol of NaOH is added to 1.0 L of a 0.2 M HCN solution. - **Acids:** [ ] - **Bases:** [ ] - **Other:** [ ]- **Solution 2:** 0.3 mol of NaOH is added to 1.0 L of a solution that is 0.8 M in both HCN and NaCN. - **Acids:** [ ] - **Bases:** [ ] - **Other:** [ ]#### Graphical InterfaceThe interface provides boxes where students can fill in the chemical species. There is also a button labeled "Check" for students to verify their answers.#### Notes- Make sure to consider the reaction between NaOH and HCN.- Remember to account for both the initial concentrations and the added NaOH when identifying species.By understanding these chemical equilibria, students can better grasp the behavior of acids and bases in solution.

ACIDS AND BASES: PROTON DONORS AND ACCEPTORS Bronsted-Lowry Theory is also called Proton Theory" of acids and bases. This theory was introduced independently in 1923 by the Danish chemist Johannes Nicolaus Bronsted and the English chemist Thomas Martin Lowry. Bronsted-Lowry Theory states that any compound that can transfer a proton to any other compound is an acid, and the compound that accepts the proton is a base. In other words, it is based on the compounds abilities to either donate or accept protons. A Bronsted-Lowry acid is proton (hydrogen-ion) donor and a Bronsted-Lowry base is a proton (hydrogen ion) acceptor. A strong acid dissociates almost completely into a proton and a weak conjugate base, while a strong base ionizes entirely, releasing OH- ion, which is a powerful proton acceptor. Expound these: "Many biological molecules are weak acids or weak bases." "The stronger the acid, the weaker its conjugate base."
