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.
The solution of this salt has a pH under 7.
Solutions with a pH less than 7 are acidic. Solutions with a pH greater than 7 are basic. Thus, a pH of 6.5 is in fact slightly acidic.
A-Strong
It's easier to change the pH of a weak acid than a strong acid.
A strong acid id PH 1 or 2 and a weak acid is a number between 5 or 6 Not 7 because that is neutral
Weak bases will have a higher H+ concentration.
pH of a strong base has larger number than a weak base...
pH of a strong base has larger number than a weak base...
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!
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
A strong acid (1 or 2 pH) A weak base ( 8 or 9 pH) The mixture would still be acidic but not as much.
NO... STRONG ACIDS HAVE A pH VALUE BETWEEN 1 AND 4 ....pH VALUES OF 5 AND 6 ARE WEAK ACIDS AND 7 IS NEUTRAL.
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 of a strong acid would be '1' or '2' pH of a weak acid would be '5' or '6' . NB 'pH' is a logarithmic scale of the hydrogen ion content of a substance. The small/bigger the number, the greater/lesser the hydrogen ion content.
pH below 7 always is acid, base has pH above 7.
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.
