Webthe acid-base reaction between HCl and NaOH produces a solution with a pH of 7 at the equivalance point (NaCl+H2O). why does an acid-base indicator that changes color at … WebDec 30, 2024 · KOH is a base. Because when it is dissolved in an aqueous solution, it gives two ions K + and OH –. And any molecule which gives OH – in a water solution is defined as a base in nature. Its pH value lies between 12-13. KOH is generally less preferred for industrial uses because of its high-cost issue. Name of Molecule. WebThe following equation is used for calculating acid and base molarity where the concentration is given in wt %: [ (% × d) / MW] × 10 = Molarity. Where: % = Weight %; d = Density (or specific gravity); MW = Molecular Weight (or Formula Weight). The above equation can then be used to calculate the Molarity of the 70 wt % Nitric Acid: death note rotten tomatoes
