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.
pH 9 is neither a strong not weak acid.
It is a weak to moderately strong alkali.
A strong acid (1 or 2 pH) A weak base ( 8 or 9 pH) The mixture would still be acidic but not as much.
Strong Acid ; pH = 1-3 Weak acid ; pH = 4-6 Neutral ; pH 7 Weak alkali ; pH = 8 -10 ( The answer) Strong Alkali ; pH = 11- 14
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"
pH 6 is a very weak acid and pH 9 is an alkaline
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.

pH 6 is a very weak acid and pH 9 is an alkaline
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
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)

that means that it DOES contain a good amount of acid. 5 or 6 is about even and 9 or 10 is hardly any
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.
Hydrobromic acid has a pKa of −9, making it a stronger acid than hydrochloric acid, but not as strong as hydroiodic acid. Hydrobromic acid is one of the strongest mineral acids known.
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.
