To calculate the pH of a buffer solution when base is added, the Henderson-Hasselbalch equation, pH = pKa + log (acid/base), is used. The mol of base is added to the buffer's base, and the base's mol is subtracted from the buffer's acid. These new mols are used to find the ...
To calculate the stoichiometry of NH3 + HOCl = H2O + NH2Cl you must balance the equation to find the stoichiometric mole ratio of each compound. The equation can be balanced using the chemical equation balancer. The stoichiometry calculator above shows the mole ratios/coefficients of the bala...
In number theory we consider indeterminate equations, that is, equations in several unknowns for which we wish to find solutions that are integers or rational numbers (seeDIOPHANTINE EQUATIONS). For example, the integer solutions of the equationx2+y2=z2are of the formx=m2–n2;y= 2mn; z...
Simplify the result to get the lowest, whole integer values. a = 1 (PH) b = 6 (AgNO3) c = 4 (H2O) d = 6 (Ag) f = 1 (H3PO4) g = 6 (HNO3) Step 4: Substitute Coefficients and Verify Result Count the number of atoms of each element on each side of the...
Henderson-Hasselbalch Equation: pH to pKa The pKa is the pH value at which a chemical species will accept or donate a proton. The lower the pKa, the stronger the acid and the greater the ability to donate a proton in aqueous solution. ...
