FEEL FREE TO EDIT OR ADD MORE TO THE SET! Weak base - a base that only partially reacts with water to produce hydroxide ions. /W 0 nitrate, sulfate): high charge, small number of oxo groups. /Type /Metadata Here are a couple of good rules to remember: Bases will not be good nucleophiles if they are really bulky or hindered. endobj >>] PDF-XChange Viewer [Version: 2.0 (Build 52.0) (Jun 7 2010; 19:37:04)] Look to your periodic table to see this arrangement: /Gamma [1.9 1.9 1.9] Some weak acids: HF, HNO 2, HClO 2, [H 2 SO 3] = SO 2 + H 2 O, HC 2 H 3 O 2 = HOAc 2.

STUDY. Strong bases are capable of deprotonating weak acids; very strong bases can deprotonate very weakly acidic C–H groups in the absence of water. Weak Bases. CsOH. Please read AddThis Privacy for more information. /WhitePoint [0.9643 1 0.8251] Strong Bases: The pKb value for strong bases is almost zero or a very low value. Various common acids and bases that you should memorize! 1: … I once saw a mnemonic device to help remember which bases are the strong bases. << The other five in the list can easily make solutions of 1.0 M and are 100% dissociated at that concentration. >> * Completely dissociated in solutions of 0.01 M or less. /Length 3160 Learn. Weak acids (which are all other acids) dissociate only a small amount. 2010-09-02T16:09:11-04:00 /Type /Pages any acid not listed above. << So a base based on some other mechanism, such as NH 3 (which does not contain OH − ions as part of its formula), will be a weak base. Strong base - a base that dissociates completely in water, producing hydroxide ions.. All the hydroxides of the Group 1 (LiOH, NaOH, KOH, RbOH, CsOH) and the Group 2 (alkaline earth - Ca(OH) 2, Ba(OH) 2, Sr(OH) 2) elements are strong bases.Although the alkaline earth hydroxides are strong bases, they are only slightly soluble. Write. 4 0 obj Ba(OH) 2. In aqueous solution, each of these essentially ionizes 100%. Examples; Weak Base: Examples of weak bases are methylamine (CH 3 NH 2), glycine (C 2 H 3 O 2 NH 2), trimethylamine ((CH 3) 3 N), hydrazine (N 2 H 4), etc. Superbases are Lewis bases that are Group 1 salts of carbanions, such as hydrides and amides.

Resonance stabilization, however, enables weaker bases such as carboxylates; for example, sodium acetate is a weak base . A weak acid or a weak base only partially dissociates. Strong Acids/Bases.
