Q. Is pH 2 an acid?
pH values lower than 7 are acidic, and pH values higher than 7 are alkaline (basic)….What does it mean for a solution to be acidic or basic (alkaline)?
| pH Value | H+ Concentration Relative to Pure Water | Example |
|---|---|---|
| 0 | 10 000 000 | battery acid |
| 1 | 1 000 000 | gastric acid |
| 2 | 100 000 | lemon juice, vinegar |
| 3 | 10 000 | orange juice, soda |
Q. What is the Colour of pH 2?
The colours from yellow to red indicate an acidic solution, colours blue to violet indicate alkali and green colour indicates that a solution is neutral. Wide-range pH test papers with distinct colours for each pH from 1 to 14 are also available….Universal indicator.

Q. What is the pH and pOH of a 0.01 M KOH solution?
pH + pOH = 14.
Q. What is the pH of a 0.10 M solution of KOH?
If concentration of KOH is 0.1 M, pH value may be 13. If concentation is 0.0001 M, pH value will be 10. Therefore, pH range of KOH solution will be 10-13.
Q. What is the pH of a 0.05 M KOH solution?
12.7
Q. Is CH3COONH4 acidic or basic?
CH3COONH4 ie ammonium acetate is a Neutral salt.
Q. What is the pH of NaNO3?
7
Q. What is the pH of k3po4?
11.8
Q. What is the pH of KF?
Anions of strong acids are such weak bases that they have no significant effect on the pH of a solution and are considered basic in water, why does KF have a pH greater than 7 and not a pH equal to 7?
Q. Is ALCL3 solution acidic or basic?
No, it means AlCl3 is a weak acid, because the only part of the molecule that is contributing to the pH of the solution is the Al+3 ion. The conjugate base of a strong acid has very little impact on the pH of the solution (with the case of Cl- and its conjugate acid, HCl).
