Explanation:
These are all good things to do in a presentation, if some teacher don't like people to tell jokes or fiddle around they can take points away from you.
Answer:
Watch some videos on complex topics you have trouble doing, and do any exercises the video links to. Read all your textbooks and test yourself, or have somebody do it for you. Read all your notes and memorize terms.
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
