Alkalinity is the ability of a solution to neutralize an acid to the equivalence point of calcium carbonate. It is not to be confused with basicity. In an academic setting, alkalinity is measured in milliequivalence per liter, and in commercial applications it is given in parts per million. A...
Calculate the pH of a buffer solution that is 0.40 M in both HC2H3O2 and NaC2H3O2. Between benzoic acid and acetic acid, which is a stronger acid without looking to pKa value? Why A buffer is prepared by mixing 44.2 mL of 0.209 M NaOH with 141.2 mL of 0.231 M acetic acid. What i...
If a solution has an H^+ concentration of 0.00000001 moles per liter, calculate the pH. Show all work. Is this solution an acid or a base? A molecule has an ionizable group with a pKa value of 8. At pH equal to 9.0, estimate roughly how much of the group is deprotonated (expres...
The ideal weight (kg) = (- 150 cm height) x 0.650, south of ideal body weight (kg) = (- 150 cm height) x 0.648, this calculation method seems to be more suitable for the north and south of Chinese. Calculate the standard weight of children, a simple method is: 1 ~ 6 months...
Moderate intake can meet the needs of the body, and will not increase the incidence of cardiovascular disease. Eat more alkaline food: normal body fluids weakly alkaline, in the exercise after the body of sugar, fat and protein are decomposed to produce lactic acid, phosphoric acid and other ...
Alowvalue of pKa(e.g. -10) indicates astrongacid. Ahighvalue of pKa(e.g. 50) indicates aweakacid. Acid base reactions have four components: anacidand abaseexchange a bond to H to give aconjugate acidand aconjugate base. Acid-base reactions can always be written asequilibria; that is...
The hydration shell of the complex H(H2O)n]+inhibits proton activity. Its value is determined by the stoichiometric water concentrationCw(mol·L–1). The equations are proposed to calculate the function: –How\\documentclass[12pt]{minimal} \\usepackage{amsmath} \\usepackage{wasysym} \\use...
like calculate what a parabola is, how fast a car is going to go, or how much money a business is going to make. Those are just mathematical calculations. Typical kinds of programs that do that are financial modeling software for simple math equations, etc. That’s the...
If a solution has an H+ concentration of 0.00000001 moles per liter, calculate the pH. Is this solution an acid or a base? What is the relationship between H+ concentration and pH value? A solution you are working with has a pH of 3. You need it to have a pH of 7....
The Role of Buffers: pH is one of the most important parameters that dictate the acidity or basicity of a solution. In cases where pH should be maintained at bay, buffers are usually added. Buffers work by preventing any significant changes in pH in case ...
