How do you tell which solution is the most acidic?
How do you tell which solution is the most acidic?
The closer the negative ion is to the H+ ion in the molecule, the stronger the acid is. Look at the strengths in the bonds between the molecules in the ion. The more lopsided it is throughout the molecule, the stronger the acid. A molecule with a triple bond is more acidic than one that only has single bonds.
Does higher pOH mean more acidic?
pH and pOH denote the negative log of the concentration of hydrogen or hydroxide ions. High pH means that a solution is basic while high pOH means that a solution is acidic. Neutral solutions have pH and pOH of 7.
What is the pOH if the pH is 3?
So, if the pH of your acidic solution is three, you can plug this in the equation above to find the pOH: Thus, For a 0.001 M solution of HCl, the pH is three, and the pOH is 11. You can also do the inverse calculation.
What is the pH of a solution with a pOH of 10?
4
| Concentration (mol/L) | ||
|---|---|---|
| [H3O+] | pH | pOH |
| 1 x 10-8 | 8 | 6 |
| 1 x 10-9 | 9 | 5 |
| 1 x 10-10 | 10 | 4 |
Which has the most acidic pH?
The scale has values ranging from zero (the most acidic) to 14 (the most basic). As you can see from the pH scale above, pure water has a pH value of 7.
How does pH relate to pOH?
The pH of a solution can be related to the pOH. Consider a solution with a pH =4.0. The pOH scale is similar to the pH scale in that a pOH of 7 is indicative of a neutral solution. A basic solution has a pOH less than 7, while an acidic solution has a pOH of greater than 7.
How are pH and pOH different?
pH refers to the “potential of hydrogen”. It can be used to determine whether a solution is acidic, basic or neutral. In contrast, pOH is a measure of hydroxide ion (OH–) concentration. The key difference between pH and pOH is that pH is a measure of hydrogen ions whereas pOH is a measure of hydroxide ions.
How is pOH related to pH?
pH and pOH are related to one another; THEY ARE NOT INDEPENDENT OF EACH OTHER. As pH increases, pOH decreases. As pH decreases, pOH increases. By knowing what ion you are measuring on which scale, this will tell you whether or not the solution is acidic or basic.
Is pOH 12 acidic?
This example illustrates the following relationship. The pOH scale is similar to the pH scale in that a pOH of 7 is indicative of a neutral solution. A basic solution has a pOH of less than 7, while an acidic solution has a pOH of greater than 7.
