calculating the concentration of hydrogen ions in weak acids is just a little trickier. These acids do not completely ionize in water. Each acid has a tendency to lose a hydrogen ion in an aqueous solution. A stronger acid is more likely to lose its ...
Calculate the force of attraction according to F = k * q1* q2/ d2. Using the previously obtained values for calcium bromide and using 8.99 x 109as the value for k gives F = (8.99 x 109) * (3.8 x 10-19) * (1.9 x 10-19) / (3.96 x 10-10)2. Under the rules of the scient...
Hydrogen ion (pH): The peripheral and central chemoreceptors are also sensitive to the pH of the blood and CSF. If the hydrogen ion concentration increases (that is, if the fluid becomes more acidic), then the chemoreceptors tell the respiratory centers to speed up. Hydrogen ion concentration...
The concentration of the alcohol in the alveolar air is related to the concentration of the alcohol in the blood. As the alcohol in the alveolar air is exhaled, it can be detected by the breath alcohol testing device. Instead of having to draw a driver's blood to test his alcohol level...
Calculate the actual concentration of this oxalic acid solution. Don't forget to look at the balanced equation. NaOH \rightarrow NaCH_3CO_2 How many moles of sulfuric acid are needed to neutralize 1,000 mL of 0.10 M NaOH? Note that ...
Fig. 2: The mechanism of probiotics to prevent dental caries. It is roughly divided into five parts.AProduction of active metabolites: probiotics directly inhibit cariogenic pathogens by active metabolites (e.g., bacteriocin, enzyme, biosurfactants, organic acids, and hydrogen peroxide), which thems...
The Kffor water is 1.86 °C/m. This number can be found in a table such as the one in the first reference. Since NaCl dissociates into two ions, the van't Hoff factor is 2. Finally, you need to calculate the molality of the solution. ...
I will ignore any common ion effect since it will be negligible (I think). The pH will be the total H+H+ concentration, so [H+]=5.624×10−10+0.15[H+]=5.624×10−10+0.15. This is a pH of about 0.823 which is totally wrong. What am I doing wrong? Also, the volumes o...
The concentration of free hydrogen atoms is what determines a solution's acidity or alkalinity. This concentration is measured by pH, a term that originally referred to the "power of hydrogen." Household chemicals that are acidic generally have a sour ta
The scales used to calculate pH and pOH are opposite sides of the same coin. While one tells you the concentration of hydrogen (hydronium) ions, the other tells you the concentration of hydroxide ions. Advertisement Usually, pH is reported on a 0-14 scale (though it is not an absolute sc...
