Calculate the ph of a solution that has [oh-] = 1 x 10-9. show work or how to do this! : )

PH + PoH is equal to 14.

You’re given the concentration of OH. Taking the logarithm of that (log [OH]) gives you PoH. Subtract 14 from answer to get PH. Hope that helps :-)

Ch4 and ph3 are both covalent since they are composed both of non-metals.    ch4 is non- polar because of  london forces and has a geometry of tetrahedral  ph3 , on the other hand, is umbrella shaped polar and has dipole-dipole intermolecular force (imf) . since ph3 is polar, it has a stronger imf
