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.
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.
A solution that has a pH of 6 is slightly acidic.
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
pH 1 is the most acidic, as it is closest to 0 on the pH scale. Lower pH values indicate higher acidity.
The ratio is 1:1 000 000.
