acidic solutions (H+)

basic solutions (OH-)
|
Detailed explanation-1: -An acid is a solution that has a higher concentration of positively charged hydrogen ions (H) than negatively charged hydroxide ions (OH). Common examples of acids are lemon juice and vinegar. A base has a higher concentration of OH ions.
Detailed explanation-2: -High concentrations of hydrogen ions yield a low pH (acidic substances), whereas low levels of hydrogen ions result in a high pH (basic substances).
Detailed explanation-3: -More concentrated electrons = more stable base = weaker acid. But electronegativity = more concentrated electrons (even though size trumps it). And electronegativity = stronger acid.
Detailed explanation-4: -At pH 7, the substance or solution is at neutral and means that the concentration of H+ and OH-ion is the same. If pH < 7, the solution is acidic. There are more H+ than OH-in an acidic solution.
