WebCalculate the ph of 0.01m solution of nh4cn 1) NH4CN is salt made up of NH4+ and CN- salt made of stronger acid and weaker base is acidic. Salt made of weaker acid and stronger base is basic. Ka of HCN (Always on Time. If you're struggling with math, there are some simple steps you can take to clear up the confusion and start getting the right ... WebA solution of a strong acid at concentration 1 M (1 mol/L) has a pH of 0. A solution of a strong alkali at concentration 1 M (1 mol/L) has a pH of 14. Thus, in most problems that arise pH values lie mostly in the range 0 to 14, though negative pH values and values above 14 are entirely possible. Weak acid/base
WebThe concentration of hydrogen ion is measured using pH scale. The acidity of aqueous solution is expressed by pH scale. The pH of a solution is defined as the negative base-10 logarithm of the hydrogen or hydronium ion concentration. pH = -log [H 3 O +] To Calculate: The pH of a 2.00 M NH 4 CN solution.
WebBecause H 3 O + concentration is known now, pH value of NH 4 Cl solution can be calculated. pH = -log[H 3 O + (aq)] pH = -log[7.42 * 10-6] pH = 5.13; Questions.
