Well, darling, something with a pH of 10.5 is considered basic. It could be a solution of sodium bicarbonate or even some soaps. Just remember, high pH means it's more basic than your average drama queen.
pH 1 is the most acidic, as it is closest to 0 on the pH scale. Lower pH values indicate higher acidity.
You can test the pH of a solution using pH strips, pH meters, or pH indicator solutions. With pH strips, you simply dip the strip into the solution and compare the color change to a pH color chart. pH meters provide a digital pH value by immersing the electrode into the solution. pH indicator solutions change color based on the pH of the solution, allowing for a visual estimation of pH.
To measure pH accurately in a solution, you can use a pH meter or pH strips. A pH meter provides a digital reading of the pH level, while pH strips change color based on the pH level of the solution. Simply dip the pH meter probe or pH strip into the solution and read the pH value indicated.
pH 0 < acidic < pH 7 neutral = pH 7 pH 7 < basic < pH 14
The lower the pH, the more acidic the solution is. Remember, pH 7.0 is H2O. As pH decreases below 7, the solution's acidity increases. As pH increase above 7, the basicity of the solution increases. Hence, in the choices you provided, pH 1.0 is most acidic.
The nominal particle size for Avicel PH 105, which is a type of microcrystalline cellulose, is typically around 50 microns.
1/103 = 0.001 M ========( pH 3 ) 1/105 = 0.00001 M ============( pH 5 ) As you see, a pH of 3 has a 100 times concentration of 5 pH ( 10 * 10 devalued ) This is the scale; logarithmic.
105+105=210.

The LCM is: 105
22% of 105= 22% * 105= 0.22 * 105= 23.1
105 over 1 105/100
31% of 105= 31% * 105= 0.31 * 105= 32.55
86% of 105= 86% * 105= 0.86 * 105= 90.3
The greatest common factor (GCF) of 105 and 210 is 105.
18% of 105= 18% * 105= 0.18 * 105= 18.9
