The ionic radius of I-is larger than that of Cl-. where can i find red bird vienna sausage? Water is a weak base, but it is a base, so it can . One of the most common antacids is calcium carbonate, CaCO3. Is an aqueous solution with H+ = 6.9 x 10-4 M acidic, basic, or neutral? It could contain either an excess of hydronium ions or an excess of hydroxide ions because the nature of the salt formed determines whether the solution is acidic, neutral, or basic. The conjugate base of an acid remains after the acid has donated what? Is SbCl5 ( Antimony pentachloride ) polar or nonpolar ? Is a solution with H3O+ = 4.21 x 10-6 M acidic, basic, or neutral? The strong bases are listed at the bottom right . Spanish Help Is an aqueous solution with H+ = 3.1 x 10-6 M acidic, basic, or neutral? document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); Address: 9241 13th Ave SW Explain. Is a solution with OH- = 1.53 x 10-7 M acidic, basic, or neutral? Is a solution with OH- = 1.0 x 10-7 M acidic, basic, or neutral? A strong acid and a weak base yield a weakly acidic solution, not because of the strong acid involved, but because of the conjugate acid of the weak base.
