Whereas, a base is a molecule or ion that can accept a proton (hydrogen ion) and is considered an electron-pair donor. Further, an acid generates H+ ions in solution and a base generates hydroxide (OH- ions) in solution.Equivalent Weight Formula How to Calculate Equivalent Weight Equivalent...
You can also calculate concentration from pH and pKa, the latter being derived from theacid dissociation constantKa. The higher the Kafor a particular acid, the stronger the acid it is. The pKafor any acid is the pH at which half of the acid has been ionized (that is, when half of t...
The hydrogen ion concentration of a solution with pH = 5.5 is 3.2*10-6M. See, this is why talking about a pH is much easier than the whole long number you got for an answer! A pH of 5.5 tells you about acidity, and you can calculate the molarity if you need it. What Do pKa Va...
pKa values have been measured for a large number of molecules and are largely related to the most acidic functional group present in the molecule. A pKa table is a useful complication of pKa values. A low value of pKa (e.g. -10) indicates a strong acid. A high value of pKa (e.g....
To calculate the fluid loss from retinal blood-brain barrier we can use Starling equation for fluid filtration (Yuan and R.R., 2010), but to do this we need to estimate driving pressures and the hydraulic conductivity for the blood-brain barrier (in units of cm3 of transudate/s/cm H2O...
A buffer is a substance that maintains the pH of a solution. Generally, a buffer contains a conjugate acid/base pair of a weak acid and weak base. If an acid is added to the solution, it will react with the weak base and the pH of the solution will change very ...
Use the data you've been given to calculate pH at each step of the reaction if the problem asks you to do so (if not, skip this step and proceed to Step 6). Depending on the identities of analyte and titrant, there are four possibilities. ...
In order to compare with our experimental results, it is easier to calculate the absolute quantity of thiol molecules needed to functionalize the AuNP contained in the initial suspension (volume V2 = 2 mL) used in the experiments. This number is simply 𝐶𝑁𝑃×𝑉2×𝑁𝑡ℎ𝑖𝑜...
