It is strongly basic at a 0.1 mol/L level. The acid [H+] concentration is 1.0*10-13 mol/L
When adding a strong acid to an acidic solution pH decreases. Adding a strong base to an acidic solution the pH increases.
Very strong acid solutions that have phenolphthalein added to them turn orange, but in general acidic solutions with phenolphthalein are colorless. If the solution is titrated to slightly basic (pH > 8.2) it will turn pink. Note that in extremely basic solutions (pH > 13) it will revert to colorless again.
No, a pH of 7.38 is slightly acidic. In pH scale, 7 is neutral, below 7 is acidic, and above 7 is basic.
Based on the Ph scale 14 is high basic 1 is high acidic then coffee should be a little acidic. But that depends probably depends on how strong the coffee is.
Very acidic.A pH of 7 is considered neutral while anything above 7 is basic (alkaline) and anything under 7 is acidic.For every number on the pH scale, the change is ten-fold. So a solution with a pH of 2 is 10 times more acidic than a solution with a pH of 3.
pH 1 is strong acidic pH 7 is neutral and pH 13 is strong alkali
When adding a strong acid to an acidic solution pH decreases. Adding a strong base to an acidic solution the pH increases.
Since in water pH < 7 is acidic and pH > 7 is basic, pH=13 is more basic than pH=1
A strong acid will have a low pH and a strong base will have a high pH.
Acidic: pH < 7 Basic : pH > 7
Very strong acid solutions that have phenolphthalein added to them turn orange, but in general acidic solutions with phenolphthalein are colorless. If the solution is titrated to slightly basic (pH > 8.2) it will turn pink. Note that in extremely basic solutions (pH > 13) it will revert to colorless again.
The pH scale goes from 0 - 14, with 7 being neutral; the lower the number, the more acidic the solution.
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.
whith PH, lower numbers are more acidic. so 1 is more acidic than 8.
No, a pH of 7.38 is slightly acidic. In pH scale, 7 is neutral, below 7 is acidic, and above 7 is basic.
Based on the Ph scale 14 is high basic 1 is high acidic then coffee should be a little acidic. But that depends probably depends on how strong the coffee is.
pH 0 < acidic < pH 7 neutral = pH 7 pH 7 < basic < pH 14
