Do bases have a high or low number
WebAn acidic solution has a high concentration of hydrogen ions (H + ^+ + start superscript, plus, end superscript), greater than that of pure water. A basic solution has a low H + ^+ + start superscript, plus, end superscript concentration, less than that of pure water.
