YES, the PH scale is 0-14 with 7 being neutral 0-6 is acidic 8-14 is basic ( alkaline ) when the PH of water is on the alkaline side of the scale chlorine is added to reduce the PH to bring it back to 7 !
No, strong acids tend to lower the pH of a solution. This is because strong acids donate hydrogen ions (H+) when they dissolve in water, increasing the concentration of H+ ions and lowering the pH.
strong acid
Strong acids would be expected to have a lower pH level compared to weak acids. Strong acids fully dissociate in water to produce a higher concentration of hydrogen ions, resulting in a more acidic solution and a lower pH.
Strong acids have a lower pH than weak acids. This is because strong acids completely dissociate in water to release all their hydrogen ions, resulting in a high concentration of H+ ions and a lower pH. Weak acids only partially dissociate, leading to a lower concentration of H+ ions and a higher pH.
Yes, strong acids dissociate more completely in water, leading to a higher concentration of H+ ions and a lower pH compared to weak acids which don't fully dissociate.
Those with a ph value of 3 or lower
Strong acids will appear at the lower end of the pH scale, typically around 0 to 3. The color associated with strong acids on pH test strips is typically a bright red to indicate the low pH levels.
Acids have pH values below 7.0. Bases have values above 7.0.
Weak acids typically have a pH greater than 3. A pH of 3 or lower is generally associated with strong acids, which fully dissociate in solution. Weak acids only partially dissociate, resulting in a higher pH compared to strong acids. Therefore, while weak acids can have a pH below 7, they usually do not reach values as low as 3.
Yes In theory, you could have a very weak solution of a strong acid and a stong solution of a weak acid and they would have the same pH.
Usually a strong acid will produce a lower pH, but not always. pH is not a measure of the strength of an acid (or base) but the acidity of a solution, which is dependent on both the strength of the acid or base and its concentration in the solution.
Lowest pH, strong acids, then weak acids, then salts of strong acids and strong bases, then salts of weak acids and strong bases, then weak bases, then strong bases. All very confusing!
