NaCHO would increase the ph of the solution
NaBr and KCl are neutral substances that cannot change the pH of the formic acid solution.
Since HCl is a potent acid, adding more of it will cause the pH of the solution to decrease even more. Regarding NaCHO, it stands for sodium citrate, which is a weak base. NaCHO can thereby increase the pH of the formic acid solution.
<h3>What is Acid and base ?</h3>
There are many different ways to define acids and bases. According to the bronsted-Lowry definition, a base is a proton acceptor, whereas an acid is a proton giver. According to Lewis, an acid is an electron pair acceptor, whereas a base is an electron pair giver.
