PH 6 is much less acidic. An example of Ph 6 is milk. Whereas Ph1 is stomach acid (very acidic) :)
pH 1 is strong acidic pH 7 is neutral and pH 13 is strong alkali
An ACIDIC Sol'n has a pH < 7. pH = 1 is strongly acidic (H2SO4/HCl/HNO3) pH = 4 mildly acidic (CH3COOH) pH = 6 weakly acidic. (H2CO3 as naturak rain water; NOT acidic rain).
1 - 6 acidic 1 being most7 neautral8 - 14 base 8 being least base 14 being most
pH is to indicate the concentration, while the 'strength' is measures by other means.
A solution that has a pH of 6 is slightly acidic.
the least acidic would be the one closest to the neutral pH number of 7 (which is the pH of pure water, NOT salt water... salt water is slightly acidic i THINK due to salt content). so in the case given in ur question, the least acidic would be the substance with pH level of 6.
1-6. 1 and 2 is strongly acidic. 5 and 6 is lightly acidic
No, an acid typically has a pH below 7. A pH of 6 is slightly acidic, but a stronger acid would have a pH closer to 1 or 2.
Substances with a pH of 1-6 are acidic in nature. Examples include lemon juice, vinegar, and stomach acid.
1-7, 7 being neutral, so maybe you would consider it 1 - 6.9
From pH 6 - pH 0. pH 0 being the most acidic.
pH 1 is the most acidic, as it is closest to 0 on the pH scale. Lower pH values indicate higher acidity.
