WebOct 8, 2024 · We know that pH + pOH = 14, so pOH = 14-pH. Also, the log_10 of Ksp = -11.25. Substituting those into the equation below yields l o g [ Mg + 2] = − 11.25 + 2 ( 14 – p H) l o g [ Mg + 2] = − 11.25 + 28 – 2 p H l o g [ Mg + 2] = 16.75 – 2 p H Or, if we multiply by -1, the left hand side is -log [Mg+2], or pC for Mg+2. WebFeb 13, 2024 · At a pH of 1, the environment is considered acidic and acetic acid exists predominately in its protonated form. At pH 8, the environment is considered basic, and … The pH scale ranges from 0 to 14, with a pH of 7 indicating neutrality, values less than 7 indicating acidity, and values greater than 7 indicating basicity. The pH scale is based on the hydrogen ion concentration, with each pH value representing a tenfold difference in hydrogen ion concentration. See more In chemistry, pH , also referred to as acidity, historically denoting "potential of hydrogen" (or "power of hydrogen"), is a scale used to specify the acidity or basicity of an aqueous solution.
