What else can I help you with?
What indicator would you use to determine the strength of a base?
Strong Acid - Strong Base titrationHCl(aq) + NaOH(aq) -----> NaCl(aq) + H2O(l) At equivalence the only species present will be NaCl(aq) & H2O(l)The solution of a salt of a strong acid and a strong base will have a pH=7NaCl(aq) will have a pH=7A suitable indicator would be bromothymol blue (pH range 6.2 - 7.6) or phenol red (pH range 6.8 - 8.4)Strong Acid - Weak Base titrationHCl(aq) + NH3(aq) -----> NH4Cl(aq) NH4Cl is the salt of a strong acid & a weak base, so a solution of NH4Cl will have a pH < 7 (NH4+ is a weak acid)A suitable indicator would be methyl orange (pH range 3.1 - 4.4) or methyl red (pH range 4.4 - 6.0)Weak Acid - Strong Base titrationCH3COOH(aq) + NaOH(aq) -----> CH3COONa(aq) + H2O(l) CH3COONa is the salt of a weak acid & a strong base, so a solution of CH3COONa will have a pH > 7 (CH3COO- is a weak base)A suitable indicator would be phenolphthalein (pH range 8.3 - 10.0) or thymol blue (pH 8.0 - 9.6)
Which label would best describe a solution with a pH of 11?
a buffer is wrong, it is basic or alkaline, depending on the choices
When a strong base is added to water does the pH drop significantly?
The pH increase significantly.
What is the pH of strontium?
Strontium does not have a pH as it is not an acid or base in itself. However, it will react with water to produce strontium hydroxide, which is a base and will produce a pH greater than 7. pH is not a measure of how strong an acid or base is, it is a measure of how acidic or basic a solution is. It depends on both how strong a dissolved acid or base is and how much is dissolved in a given volume of water.
What solution would require the greatest amount of base to be added to bring the solution to neutral pH?
To determine which solution would require the greatest amount of base to reach a neutral pH, you would look for the solution with the lowest initial pH. For example, a strong acid solution, such as hydrochloric acid (HCl) at a low concentration (e.g., pH 1), would require significantly more base to neutralize it compared to a solution with a pH closer to neutral, like a weak acid solution. The greater the acidity (lower pH), the more base is needed to achieve a neutral pH of 7.
Is strong base on the pH scale is it 3?
Bases run from 7.1 to 14 on the ph scale. A strong base would be in the 12-14 range. A 3ph is a relatively strong acid.
If a liquid is a strong base what is the pH?
A strong base would be around from 1-3 on the pH scale.
The pH of a strong base would be?
14
Would a pH of 10 would indicate that you had a strong base?
Not necessarily. Although a very dilute strong base can produce a pH of 10, so can a weak base such as ammonia.
What PH would be considered a strong base?
A strong base would have a pH value ranging from 10 to 14. Examples of strong bases include sodium hydroxide (pH 12-14) and potassium hydroxide (pH 12-14).
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 bases have a pH below 7?
No. Strong bases wold have a pH above 8 or 9. A pH of 13 would be a very strong base.
Is pH12 a strong acid?
No, pH 12 indicates a strong base, not a strong acid. A strong acid would have a pH value below 7.
How do you tell a strong base from a weak base?
A strong base is any Metal Hydroxide of groups I and II on the periodic table. The pH has nothing to do with it because you can take a weak base and heavily concentrate it and it will have a high pH, while you could take a strong base and dilute it and it would have a low pH.
A very strong base would have a pH close to?
The strongest bases are pH 13 or 14.
What is the pH score for a strong acid and a strong base?
A strong acid will have a low pH and a strong base will have a high pH.
What is the pH of the strongest base on pH values?
The strongest base on the pH scale is typically around 14. This means that a strong base would have a pH value of 14. Examples of strong bases include sodium hydroxide (NaOH) and potassium hydroxide (KOH).
