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)
A solution with a pH of 14 is a strong?
A solution with a pH of 14 is a strong base. A pH of 7 is neutral, a pH less than 7 is an acid, and a pH greater than 7 is a base.
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.
When an strong acid and weak base meet What is the pH?
The pH that results when a strong acid and strong base are mixed will depend on the moles of acid and moles of base present. One cannot predict the pH without knowing, or being able to calculate, the moles of each.
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.
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...
How does the pH of a strong base compare with the pH of a 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 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.
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.
Does a pH of 12 indicate a strong or weak base?
pH =12 is a very strong base. The high value pH is #14#.
What is the Ph level of a very strong base?
The stronget base would be something like lye with a Ph level of 14.
A very strong base would have a pH close to?
The strongest bases are pH 13 or 14.
What pH value represents a strong base?
A strong base has a pH level from 12-14.
