3. pH is a negative logarithmic scale. Therefore a difference of 100 times more is translated to -log(100) = -2. Recall the formula pH = -log([H+]).
The ratio is 100:1.
The oxygen diffuses through the thin lining of the alveoli into the blood. It moves from the area of high oxygen concentration (the alveoli) to the area of low oxygen concentration (the blood).
The highest concentration of cones in the retina is 50 per 100 micrometers in the central fovea. (from wikipedia) So there are approximately 17,500 cones in central fovea.
Type your answer here... it is 56 percnt of total body fluid .body contains 100 trillions of cells out of these 25 trillions r rbc
Isotonic saline is 0.9% saline. Thus, when receiving IV fluids, Normal Saline is often given at a concentration of 0.9% as to be isotonic with blood. Other medical applications necessitate the administration of hyper-/hypotonic saline solutions that would induce various osmotic shifts.
The pH scale represents a count of ions (hydrogen), or more accurately the "activity" of hydrogen ions. The pH is the negative of the logarithm (base 10) of the concentration in moles per liter. A solution with a pH of 4 is 100 times as concentrated as one with a pH of 6.
100 times
Each step in pH represents a 10x concentration difference of H+ (protons). From pH3 --> pH5, there are 2 10x concentration differences of H+. Therefore, there is a x10^-2 difference Formula is: pH=-log (base 10) [H+]
The H3O+ concentration in a solution with pH 3.22 = 1x10^-3.22 M or 6.03x10^-4 M.If a solution is 100 times less acidic, then the H3O+ concentration will be 6.03x10^-6 M.Put another way, 100 times less acidic will have a pH of 5.22 and H3O+ = 1x10^-5.22 = 6.03x10^-6M
there are more H+ ions in a pH 2 solution that in a pH 4 solution. The hydrogen ion (H+ ion) is responsible for the acidity of a substance and so, the more of it there is, the more acidic it is (higher acidity= lower pH) :)
The pH of such a solution would be 6.
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.
Ammonium chloride dissociates 100% into ions in solution. The ammonium ions interact with the hydroxide ions from the water removing them from the solution. This increases the concentration of hydrogen ions, increasing the acidity of the solution. We say that a solution of ammonium chloride is acidic by hydrolysis.
100 times more Hydrogen ions are in solution of pH=5 as compare to pH=7.
Because of the logarithmic nature of the pH scale, a single step indicates a difference tenfold. As such, the difference in concentration of hydrogen ions between solutions A and B in this example are a hundred fold, with solution A having a higher concentration than solution B.
concentration of OH- is 100 times greater than what it was at PH 5
