Webb16 dec. 2016 · pH = −log10[H 3O+] = 13.84 Explanation: In 1 mL of solution, [N aOH] = moles of NaOH volume of solution = 1.01 ⋅ g ×3.85% 56.11 ⋅ g ⋅ mol−1 × 1 1 × 10−3L = 0.693 ⋅ mol ⋅ L−1 Now pOH = −log10[H O−], pOH = −log10(0.693) = 0.159 But in water, we know that pH + pOH = 14, And thus 14− 0.159 = pH = 13.84 Webbחומצת מימן כלורי (קרויה גם חומצת מלח, חומצה מלחית, חומצה הידרוכלורית (Hydrochloric acid), מי אש וחומצה מוריאטית (Muriatic acid)) היא חומצה הנוצרת כשהגז מימן כלורי מתמוסס במים.הגז מורכב מאטום אחד של מימן ואטום אחד של כלור, ונוסחתו: HCl.
