What pH is a weak alkali?
any concerted alkali is weak alkali
What happens when a strong acid mixes with a weak base?
When a strong acid mixes with a weak base, the acid will fully dissociate into ions while the weak base will partially react, leading to the formation of water and a salt. The resulting solution will be more acidic than basic due to the excess of hydrogen ions from the acid.
What is the pH level of table sugar?
i am trying to find out. is it an strong/weak acid, or netural, or strong/weak base :s Yarma said: "I think it's 9"
What is the pH difference between a strong base and a weak base on the pH scale?
If you are using the common English definitions of "strong" (meaning 'more') and "weak" (meaning 'less'), then a strong base will have a pH of 12-14 while a weak base will have a pH of 7-9. However, there is a specific scientific definition of 'strong' and 'weak' when used to describe acids and bases. In chemistry, a 'strong base' is a base that completely ionizes in water while a 'weak base' is a base that partially ionizes in water. If you are using these definitions, there is no way to categorically compare the pH of a strong base versus the pH of a weak base - the two variables do not related. Some strong (complete ionization) bases will have a lower pH (7-9) while other strong (complete ionization) bases will have a higher pH (12-14); the same is true of weak (partial ionization) bases.
Is ammonia or vinegar more acidic?
An acid is a substance which releases H+ ions when dissolved in water (i.e when in aqueous state). Vinegar is a an acid, with a pH of about 2. On the other hand, ammonia is a weak base, with a pH of about 9.

Is weak acid on the pH scale is 3?
Yes, a weak acid with a pH of 3 indicates that it is slightly acidic. A lower pH value indicates higher acidity. Weak acids only partially dissociate in water, resulting in a lower concentration of hydrogen ions compared to strong acids.
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)

What is a pH scale How do you make a pH scale pls answer FAST?
its something used to see whether a substance is an acid or alkali. the scale is as follows 1-3 is a strong acid 4-6 is a weak acid 7 is neutral (distilled water) 8-9 is weak alkali 10-14 is a strong alkali
How do you make pH 9 buffer solution?
To make a pH 9 buffer solution, you can mix a weak base like sodium bicarbonate (NaHCO3) or sodium carbonate (Na2CO3) with its conjugate acid. Adjust the concentrations of the base and acid to achieve a pH of 9 using a pH meter for precise measurements.
What describes a solution of a pH lower than the pH of distilled water?
pH Scale of Water is 7, the color of this IS green. So anything that has a pH scale of under 7 is an acid. Anything with a pH scale over 7 is a alkali. This the pH ruler. 1 2 3- Strong Acid 4 5 6-Weak Acid 7 -Neutral 8 9 10- Weak Alkali 11 12- Strong Alkali Tip: If you get stung by a wasp, you should try using a vinegar to make it neutral. If stung by bee use a soap. This works because bee has acid and wasp is alkali. By putting the right amount of alkali or acid to either of your insect sting, you should be able to take away the pain.
Is toothpaste a strong alkali or a weak?
Toothpaste is slightly basic, but it is not considered a strong alkali. The pH of toothpaste typically ranges from 7 to 9, which is mild compared to strong alkalis like sodium hydroxide or ammonia.
