Rubbing alcohol is diluted isopropanol. The formula for isopropanol is (CH3)2CHOH or simply C3H8O.
The pH of hydrogen peroxide at concentrations of 10% to 12% is around 3.0 to 4.0. It is considered acidic.
BTB (bromothymol blue) is a pH indicator that turns yellow in acidic conditions (pH < 6) and blue in basic conditions (pH > 7.6). Rubbing alcohol is typically neutral in pH (around 7), so when mixed with BTB, the color would likely remain green due to the pH of rubbing alcohol not significantly affecting the indicator.
the pH
The neutral pH is 7,00.
The highest number on the pH scale is 14. The pH scale goes from 0 to 14.
the pH level of isopropyl alcohol is 5.5
Rubbing alcohol typically has a pH level around 5.5-6.0, making it slightly acidic.
Most, if not all alcohols are neutral, so they have a pH of 7.
The pH of pure ethanol and all other alcohols is 7, because the pH (power of Hydrogen) number refers to the number of OH- or H+ ions in a solution*, neither of which are present in any alcohols. Pure alcohols therefore, are neither acids nor are they bases. Most alcohol solutions are (very) weakly acidic. *Some Acids and Bases are composed without these two ions, but for the purposes of this question, this definition is usable, even though not technically correct.
It's neutral because on the pH table it's pH 7.
The pH value of isopropyl alcohol is around 7, which is considered neutral. This means that isopropyl alcohol is neither acidic nor basic.
NO
Alcohol is only slightly acid because it's pH is about 5.5.
You can convert pH to Percent dissociated easily using the Ka value. You can calculate the [H+] from the pH value, the [A-] from stoichiometry, and the [HA] from all of the above. It is easy to find the percent dissociation from here.
The pH of hydrogen peroxide at concentrations of 10% to 12% is around 3.0 to 4.0. It is considered acidic.
Ammonia has a higher pH compared to battery acid, isopropyl alcohol, and water. Ammonia is a base with a pH usually above 11, while battery acid, isopropyl alcohol, and water are either neutral or acidic in nature.
