What else can I help you with?
If a substance has a pH of 1 is it a strong or weak acid?
Strong because a substance with a pH of 7 is considered neutral, so the further away from 7 the pH gets, the more strong of an acid it becomes.
What is the pH of salt made from a strong acid and weak base?
The solution of this salt has a pH under 7.
If a substance has a pH of 6 is it a strong or weak acid?
A substance with a pH of 6 is considered acidic, but the strength of the acid cannot be determined solely from its pH value. To determine if it is a strong or weak acid, additional information such as its dissociation constant (Ka) or the specific type of acid would be needed.
Show my the pH chart by strong and weak acid?
A strong acid completely dissociates into an H+ ion and an anion. pH is defined as pH = -log(H+ concentration) So if you have 0.01 mole hydrochloric acid (HCl) per 1 mole solution, since each mole HCl contributes a mole of H+ and a mole of Cl- then you would have H+ concentration of 0.01 pH = -log(0.01) = -(-2) = 2, so the pH = 2 Note that higher H+ concentrations result in lower pH number
Does the addition of water (baking soda plus water) alter the pH of weak acidsbasesHow does it changethe pH of srong acidsbases Why or why not?
The addition of water to weak acids or bases generally dilutes the solution, which can lead to a slight increase in pH for weak acids and a decrease in pH for weak bases due to the equilibrium shifting. In contrast, adding water to strong acids or bases typically results in a more significant change in pH, as strong acids and bases dissociate completely in solution. Therefore, dilution with water for strong acids will lower the pH (less acidic) and for strong bases will raise the pH (less basic) but will still remain strongly acidic or basic depending on their original concentration. Overall, the extent of pH change depends on the strength and concentration of the acid or base involved.
How does the pH of a strong base compare with the pH of weak base?
pH of a strong base has larger number than a weak base...
Do strong acids have a higher or lower pH than weak acids?
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.
How does pH of a strong acid compare with the pH of a weak acid?
i think a strong acid ionizes completely in water while a weak acid ionizes partiallly in water therefore the pH of a strong acid is greater than that of a weak acid The first part of your answer was correct, but the second was reversed. The pH of a strong acid is lower than the pH of a weak acid.
Is alkali an acid?
No. Alkali's and acids are an separate ends of the pH scale, the pH of acids being 1, 2, 3, 4 and 5 (strong to weak) and the pH of alkali's being 11, 12, 13, 14 and 15 (weak to strong). Examples of acids are hydrochloric acid (strong) and vinegar (weak). Toothpaste is an example of a weak alkali.
What pH is a weak alkali?
any concerted alkali is weak alkali
What is the lowest pH to the highest pH?
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!
What is pH of a strong acid and pH of a weak acid?
The pH of a strong acid is typically close to zero, as strong acids completely dissociate in water to release H+ ions. The pH of a weak acid is usually higher than zero, as weak acids only partially dissociate in water, resulting in a lower concentration of H+ ions and a pH closer to 7.
What factors determine pH of buffering?
If a strong acid is mixed with a weak base, pH=pKa+/-1 in the buffer region.Corrected:If a strong base is mixed with a weak acid pOH= pKb +/-1 ( pH=(14 - pKb)+/-1) in the buffer region[Remember: For one conjugated pair of weak acid (a = HB) AND its weak base (b = B-):pKa + pKb = 14.0andpH + pOH = 14.0
Is it possible for a strong acid and a weak acid to have the same pH?
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.
How does the pH level of a strong base compare to a weak bases pH?
The pH is higher.
Citric acid has a pH between 1 and 3 It is considered to be a?
strong acid
Is pH 9 a strong or weak acid?
A pH of 9 is not acidic, it is basic. in order to be acidic the pH must be less than 7 It does not show whether the base is strong or weak as pH depends on both the strength of the acid/base as well as its concentration.
