What is the pH of 8×10 8 M HCL?
The pH should be 7.1 guys. Simple is that we’re all done again. This is really simple because we have a strong acid.
Can you have a negative pH?
Thus, measured pH values will lie mostly in the range 0 to 14, though negative pH values and values above 14 are entirely possible. Since pH is a logarithmic scale, a difference of one pH unit is equivalent to a tenfold difference in hydrogen ion concentration.
What is the pH of a 0.0075 M solution of HCL?
Mike Schuck · Ernest Z. The pH is 1.60.
Why is HClO4 an acid?
HClO4 is considered an acid because on dissolving in an aqueous solution it dissociates into two ions (H+ and ClO4–) and anything that release proton ion in solution considered as the acid in nature. 1 Why HClO4 is an acid?
Why is HClO4 a strong acid?
Hclo4 is more acidic all of the them because Oxygen is more electronegative and shows four different resonating structures. In water both HClO3 and H2SO4 are equally strong acid(Levelling effect). However in other solvent like acetic acid, H2SO4(pKa=- 3) is stronger acid than HClO3(pKa =-1).
Why is HClO4 an Arrhenius acid?
Formula | Name |
---|---|
HClO4 | perchloric acid |
H3PO4 | phosphoric acid |
H2SO4 | sulfuric acid |
H2SO3 | sulfurous acid |
How do you find pH from pKb?
- Find the [OH-] from the pKb value (in the same way as for weak acid type calculations)
- From the [OH-] find the pOH.
- Find the pH from: pOH + pH = 14.
How do you calculate pKb?
To get the pKb of the base (B) you MUST subtract the pKa from 14. The reason for this is that the pOH is actually what equals the pKb. pKb = 14 – pKa H+ in EXCESS that has been added.
What is the pH of 0.00125 M HCl solution?
Hence the pOH of a 0.00125 M solution of HCl in water is 11.1.

How do you find the pH of a HF solution?
- HF→H++F−
- The pH of this solution could be found by: pH=−log[H+] .
- We will need to find the [H+] using ICE table:
- Solve for x=1.7×10−3M.
What is the pH of 1.0 M HNO3?
What is the pH of 1.0M HNO3 (AQ)? – Quora. pH = log (1/[H+]); or minus the log of the hydrogen ion concentration where the concentration refers to the molarity (more strictly, the activity). The obvious answer is a pH of zero when substituting the 1M value into the definition of pH.
Does HF have a low pH?
HF has a higher degree of attraction between the H+ and F- and so does NOT dissociate completely in water, therefore the H+ concentration is lower and the pH is higher. *pH is the measure of the hydrogen ion concentration, i.e., H+ concentration.
What type of acid is hclo4?
Perchloric acid is a chlorine oxoacid. It is a conjugate acid of a perchlorate.
Is perchloric acid a binary acid?
Simple acids, known as binary acids, have only one anion and one hydrogen. … Therefore, HClO4 is called perchloric acid. With one fewer oxygen than the “-ate” ion, the acid will have the suffix “-ous.” For example, chlorous acid is HClO2.
Is chloric acid a strong acid?
The list of strong acids consists of seven main acids – chloric acid, hydrobromic acid, hydrochloric acid, hydroiodic acid, nitric acid, perchloric acid, and sulfuric acid.
