What is the optimum ph of a sodium formate/formic acid buffer? (for formic acid, ka = 1. 7 × 10–4. )
hoa [83]

The optimum pH of formic acid - formate buffer is 3.75

<h3>What is pH? </h3>
  • pH is a measure of how acidic/basic water is. The range goes from 0 - 14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base.
  • pH is really a measure of the relative amount of free hydrogen and hydroxyl ions in the water.

What is Buffer ?

A substance or a solution which resists any changes in pH, when acid or alkali is added to it.

pH = pKa + log[base] / [acid]

Considering equimolar concentration of acid and base

pH = 3.75 + log(x)/(x)

pH = 3.75 + log (1)

pH = 3.75 + 0

pH = 3.75

Hence,

The optimum pH of formic acid - formate buffer is 3.75

How can the rescue workers get enrgy to the batteries in their equipment during rescue missions.
Ipatiy [6.2K]

Answer:

a generator that allows them to convert kinetic energy into potential energy

Explanation:

Rescue workers can accomplish this by using a generator that allows them to convert kinetic energy into potential energy. Such as a crank generator, with these, they spin a crank with their hands and the generator takes that kinetic energy that is building up through the work that the rescuer is exerting and converts it to potential electric energy that can properly be used to provide energy to the batteries for their equipment. This is what is generally used for situations such as what rescuers go through when there is no electricity around.
