Phenolphthalein has a pH of 9.7. It colorless in its acid form. It has a pinkish type color in its basic or normal form.
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.
its about 10.5 to 11
ph: 09098 97 11 28 This is a very good hospital which a highly recommend :)
97
97 + 97 = 194
97 percent out of 100 = 97 97% * 100 = 97%/100% * 100 = 97
The prime factors of 97 are 1 and 97. Thus, 97 is a prime number.
97+(20/100)*97 97+.20*97 97+19.4 116.4 Pounds
97% = .97

pH 1 is the most acidic, as it is closest to 0 on the pH scale. Lower pH values indicate higher acidity.
15% off of 97 = 82.45= 97 - (15% * 97)= 97 - (0.15 * 97)= 97 - 14.55= 82.45
pH=6,4
