Determine the ph of an hf solution of each of the following concentrations.
Leokris [45]

The pH shows the degree of acidity of alkalinity of a solution. The pH of the HF can be obtained from the ICE table.

<h3>What is pH?</h3>

The term pH refers to the hydrogen ion concentration of a solution. Recall that acids produce hydrogen or oxonium ion in solution.

The first step to determine the pH of the HF solution is to set up the ICE table as shown;

             HF + H2O  ⇄ H3O^+ + F^-

I

C

E

The values of the initial concentration of HF  as well as the Ka of HF are not given. If these two values are give, the pH can be obtained from;

Ka = [H3O^+] [ F^-]/[HF] Knowing that  [H3O^+] = [ F^-] = x

In this context, we can infer and logically deduce that Teflon is simply a type of polymer, synthetic polymer or additional polymer in industrial chemistry.

In conclusion, it is very important to note that it is completely false and incorrect to say that Teflon is simply a type of:

  • Nylon.
  • PVC
  • Elastomer.
  • Synthetic rubber
