  • योग्य उत्तर पर्याय 4 आहे, म्हणजेच 1000 पट कमी होते.
  • जेव्हा त्याचा pH बदलून 6 होतो, तेव्हा H+ आयन संहती 1000 पट कमी होते.
  • pH हायड्रोजन आयन संहती स्पष्ट करतो, pH जितका कमी तेवढीच, हायड्रोजन आयनची संहती जास्त असते.
  • आम्लांचा pH 1 ते 6 पर्यंत असतो, pH 7 उदासीन द्रावण दर्शवतो आणि 8 ते 14 च्या श्रेणीतील pH आम्लारी दर्शवतो.
  • pH ची गणना करण्याचे सूत्र हे आहे: pH = - लॉग [H+]
    • 3 चा pH = 10-3 H+
    • 6 चा pH= 10-6 H+
  • वरील मूल्यांवरून, आपण स्पष्टपणे पाहू शकतो की H+ आयन संहती 1000 पट कमी होते.
