WebMar 4, 2015 · What volume of $\pu{0.300N}\, \ce{NaOH}$ would be needed to bring $\pu{16.0 mL}$ of distilled water that has a $\mathrm{pH}$ of $7.00$ to a new $\mathrm{pH}$ of $12.42$? This is my attempt at a so... WebWhat is the pH of a buffer solution that is composed of a weak acid (HA; Ka = 6.03 × 10–7) and the conjugate base (A–) after 2.05 mL of 0.093 M NaOH solution is added. The initial concentrations of the 170 mL buffer solution are [HA] = 0.49 M and [A–] = 0.69 M.

What is the pH of a 3.9*10^-8 M NaOH solution? Socratic

WebDec 16, 2016 · To find the concentration of hydroxide anions starting from this equation, rewrite it as log([OH−]) = − pOH 10log([OH−]) = 10−pOH this will get you [OH−] = 10−pOH → remember this equation! In your case, you have [OH−] = 10−4.6 [OH−] = 2.5 ⋅ 10−5M −−−−−−−−−−−−−−−−−−− I'll leave the answer rounded to two sig figs. Answer link WebKnowing the dependence of pH on [H + ], we can summarize as follows: If pH < 7, then the solution is acidic. If pH = 7, then the solution is neutral. If pH > 7, then the solution is basic. This is known as the pH scale. You can use pH to make a quick determination whether a given aqueous solution is acidic, basic, or neutral.
