WebExpert Answer. a. Number of moles of HBr before reaction:Number of moles of HBr = concentration …. The reaction of the strong acid HBr with the strong base KOH is HBr(aq)+KOH(aq) HOH(l)+KBr(aq) Compute the pH of the resulting solution if 59 mL of 0.70M acid is mixed with 29 mL of 0.44M base. WebAcid Value (AV) The Acid Value is the number of milligrams of potassium hydroxide (KOH) necessary to neutralize the fatty acids in 1 gram of sample. Higher AV materials allow faster appearing but less stable suds creation. Lower AV materials allow slower to appear but more stable suds formation. Lower acid value means more cleansing (detergency). WebOct 21, 2024 · Swedish Svante Arrhenius, in 1884 proposed the concept of acid and base based on the theory of ionization. According to Arrhenius, the acids are the hydrogen-containing compounds which give H+ ions or protons on dissociation in water and bases are the hydroxide compounds which give OH− ions on dissociation in water. This concept is … oxford 310 maxx
