The pH scale typically runs from 0 up to 14. But how am i supposed to know the pH if i don’t know the … Therefore, the OH- concentration for Ca(OH)2 will be double that of RbOH. Asked by Wiki User. HClO4 has the lowest pH--> All acid with anion ClOX (Where X is a number between 1 to 4) will get stronger as X increase. Thus, in most problems you will deal with pH values lie mostly in the range 0 to 14, though negative pH values and values above 14 are entirely possible. A neutral pH is green coloured on the pH scale. … mol−1 Appearance white solid, hygroscopic: Density: 3.1 g/mL at 25 °C Melting point: 382 °C (720 °F; 655 K) dec Boiling point: 1,390 °C (2,530 °F; 1,660 K) Solubility in water. I know the most acidic solution has the lowest pH and the most basic solution has the highest pH. If you were to use 0.100M solutions for instance, the concentration of OH- would be greater for RbOH and it would have the greater pH. Oct 17, 2011 .
