1 millimolar = 0.001 M NaOH ( a base, remember )
- log(0.001 M NaOH)
= 3
14 - 3
= 11 pH

Do acids have a high or low pH scale?
an acid is on the left side of the scale. that means the low nubers like 1,2,3. bases are on the right side or high numbers like12,13,14. did you knowthat 14 is the highest number it can go ( that I know of).
Can NaOH and pepsin cause digestion?
No is the answer. Sodium hydroxide is is such a strong alkali that it will 'burn' the cells just like acid does. So it is not found in body. Instead you have sodium bi carbonate. But you have very strong acid in stomach. Hydrochloric acid. Imagine acidity go on increasing ten times as you go from 6 to 5 and 5 to 4. And pH in stomach is 1 to 2. (Why does not stomach is 'not' charred at this pH ?) Pepsin works in high acidic pH only and almost stop working at 5.5 pH. So no question of digestion in sodium hydroxide, which is strong alkali with very high pH. If you lower the pH pepsin starts working again.
The pH of your stomach must be?
around 1-2 is the pH of stomach acid
At what pH does acid water becom dangerous for plants?
Between the pH of 1-4.
Charge of amino acid at pH 1?
Positive.
What is the PH of 1 M NaOH?
base
What is the pH of 0.1m NaOH and 0.05m NaOH?
Supposed the acid and base are both strong: pH of the acid is 0.0 and the pH of the base (hydroxide) is 14.0
What is the pH level of naoh?
That depends on it concentration. 1 mole per liter NaOH (=40g/l) has a pH value of 14. 0.1 mole per liter has a pH of 13; 0.01 mole per liter gives pH=12, ...
Which has higher pH value 1M HCl or 1 M NaOH solution?
THE PH VALUE ACIDIC SOLUTION VARIOUS FROM 0-6.9, WHILE THE BASIC SOLUTION VARIOUS FROM 7.1-1.4. THUS ,OUT OF HCL AND NaOH WILL HIGHER PH VALUE
What is the H3O in 0048 M NaOH solution?
- log(0.048 M NaOH) = 1.3 pH --------------need Molarity? 1/10 1.3 = 0.050 M H3O ---------------------
What is the strongest acid nh3 hcl naoh h2co3?
Strongest Acid is HCl. Then in order of acidic strength H2CO3 , NH3(solution) and finally NaOH. In words, Hydrochloric Acid ; pH = 1 Carbomic Acid ; pH ~ 5 Ammonia solutioon ; pH ~ 8 or 9 Sodium Hydroxide ; pH ~ 12
How do you get pKa with the pH of a solution?
pKa= pH - log(A/HA) to clarify -log is subtract log E.g A buffer is prepared by adding .15 M of NaOH and .1 of a weak acid, HA. If the pH of the buffer is 8.15, what is the pKa of the acid? pH= 8.15 - log .15/.1 = 7.97
How many grams of NaOH must be added to 0.250 L of water to form a solution of pH equals 10.0?
a pH=10 solution of NaOH should contain 0,0001 moles of NaOH/liter. (1 mole/liter for pH=14, 0,1 for pH=13, etc.) A mole of NaOH is 40g-s. (Na=23g O=16g H=1g) 0,0001 mole is 0,004gs. You need the amount necessary for a quarter of a liter, so you divide by four. The result is that you need 0,001gs of NaOH. So if you need to make that solution without any precise laboratory equipment, you should make much larger quantities and just measure 0,250 l-s.
Is a substance with a pH of 14 a strong base?
The pH is the cologarithm of the activity of hydrogen ion in solutions; pH 14 is the pH of a strong base.
What is a strong base of pH range?
pH depends on concentration. Strong bases are for example: NaOH KOH Ca(OH)2 http://en.wikipedia.org/wiki/Base_(chemistry)
What is the pH of 0.15 M NaOH?
pH 1 to 2.Sulfuric acid is a strong diprotic acid: [H+] = 2* 0.15 = 0.30 mole/L H+pH = -log 0.30 = 0.52pH 2.
What is the mass of 3.42 moles of NaOH?
3.42 moles NaOH (39.998 grams/1 mole NaOH) = 137 grams NaOH
