Compare solutions 2 and 4 how does the common ion effect influence the pH of solution 4. explain fully and calculate the expected pH of each of these solutions?
pH contribution only comes from dissociated H+ / OH- Common ion effect affects the kDiss calculation used to calculate the H+ conc
Two clear solutions are placed in separate beakers the first solution as a pH of 4 and the pH of the second is unknown if the two solutions are mixed and the resulting pH is 5 the second solution must?
a higher concentration of OH- ions
What is the difference in hydrogen ion concentrated between solutions with pH 4 and pH 5?
A factor of 10 is the difference in a pH of 4 and a pH of 5 regardless of what the solution is.
Is the buffer supposed to keep the pH of a solution at 7?
Some buffer solutions maintain pH at 7, but others have different pH values. It is common to have buffers with pH values of 4, 7, and 10 for calibrating pH meters, for example.
A solution that is a 4 on the pH scale is what?
A solution with a pH of 4 is considered acidic. It has a higher concentration of hydrogen ions (H+) compared to a neutral solution with a pH of 7. Solutions with pH values below 7 are progressively more acidic, while those above 7 are progressively more basic.
What would be the nature of solutions with pH of 4 and 12?
pH 4 = acid pH 12= base

When working in the laboratory you discover that the solutions you are working with are tomato juice with a pH of 4 and soap with a pH of 10 By comparing the pH of these?
Tomato juice is acidic, soap is basic.

What is pherolpthalein indicator?
Phenolphthalein (3,3-bis(4-hydroxyphenyl)isobenzofuran-1(3H)-one) is a pH indicator or an indicator in volumetry; the color is pink in basic solutions and is colorless in acidic solutions.
How do you make numbers 22 with four fours?
There are a few possible solutions for this problem. Some of the solutions include: 4 x 4 + 4 + sqrt(4) = 22 44 x sqrt(4) / 4 = 22 4! + 4 - 4 - sqrt(4) = 22 There may be several other solutions.
How is acidity related to the pH value of a solution?
The pH scale measures the acidity of a substance. It ranges from 1-14. 7 is neutral, anything below that is acid. The lower the number the more acidic the substance is. If it is higher than 7 it is alkali, which means it is a base. And the opposite of acid, the higher the number the more alkali it is.
How much stronger is pH 9 than pH 4?
pH 9 - pH 4 = pH 5 It is stronger by 5 pH.
