 another name for molar molarity (mol/L) 1) -formula for pH from molarity of an element or substance? & -formula for pH from H+ concentration? pH=-log[H+] B-L (Bronsted-Lowry) acid & base def? Acid: proton/H+ donor. Base: proton/H+ acceptor. Write the conjugate pair of HClO4^-, & NH3. H2ClO4, NH4^+ Formula for H from OH? OH+H=14, so subtract the one you don't have from the one you do. Who's definition of Acids and bases is: Acid: a substance that produces H+ ions in aqueous solutions Base: a substance that produces OH- ions in aqueous solution. Arrhenius's definition Is water a proton donor or acceptor? both.  H2O will auto-ionize to form H3O+ and OH- formula for acid strength and acid ionization constant (K). Products/reactant or [A][B]/[C] when C->AB How to you write the charge on a molecule in "mastering chem" HN4+ Don't use the one that puts the superscript and subscript vertical. draw the conversions from  pOH, H+, OH, pH. how do you convert moles (M) of a substance to H+, for example? What's the pH of 0.65M of HBr? -log(0.65)=.19 (sounded up for 2 SF) How do you calculate the the ph of a molecule for a base or an acid based on it's moles (M)? Acids are calculated using [H], and bases are calculated using [OH] find the Kw for a solution with the pH of 7.41 at a given temperature. 107.41=3.89*10-8M [H+]2=1.51*10-15 Kw=[H+][OH-]=10^14 Authorstudysuccess ID313904 Card SetOSU Ch 123 DescriptionOSU Ch 123 Updated2016-01-11T00:49:11Z Show Answers
