The precise value given in the metareg immediately prior to the above ereturn information is 0.1836 Q_p - The value of P for Q I calculate is given by the formula above, that is it works with this example but is the procedure correct? The precise value given by metareg immediately prior...
The pH value of a 1% solution (pH = 9.24) is quite a sufficient approximation to calculate the pH changes after adding small but known amounts of acid or base to this buffer solution provided that we know the initial molar concentration of borax. Do you mean that adding small amounts of...

The letters pH stand for "power of hydrogen" and the numerical value for pH is just the negative of the power of 10 of the molar concentration of H+ ions.To calculate the pH of an aqueous solution you need to know the concentration of the hydronium ion in moles per litre (molarity)....
3) The Value Of A College Degree Is Equal To Its Net Present Value Of Future Cash Flows The most accurate way to calculate the value of a college degree is to conduct a net present value (NPV) calculation. In the NPV formula, all future cash flows (CF) over some holding period (N)...
pH Scale: Any system in which water is present will contain some molarity values of hydrogen and hydroxide ions. They always occur in pairs due to the self-ionization equilibrium of water. From the hydrogen ion molarity one can calculate a pH value, which is important ...
The problem is that when the image is rotated its translate(x y) values no longer corresponds relative to the area's x/y coordinates. I've found a couple of examples on how to calculate the x/y coordinates of the four corners of a rotated square or rectangle using the radians...
How to calculate concentration of NaOH in titration? Acid-Base Titration: Titration is an analytical technique used in chemistry that allows for the determination of an unknown quantity or a concentration of an analyte using a known concentration of a titrant. A titrant is a solution that reacts...
Finding the pH of a weak acid is a bit more complicated than finding pH of a strong acid because the acid does not fully dissociate into its ions. The pH equation is still the same (pH = -log[H+]), but you need to use the acid dissociation constant (Ka) to find [H+]. There ...
