Given the following equations, identify the Lewis Acid and the Lewis Base: A.) 2 Cl^- + BeCl2 -> BeCl4^-2 B.) Mg^+2 + 6 H2O -> Mg(H2O)6 ^+2 C.) F^- + BF3 -> BF4^- Classify each of the following species as a Lewis acid or a L...
A substance can be classified as an acid or base based on whether a proton is accepted or donated. A proton can be denoted as {eq}H^+{/eq} which is also known as the hydrogen ion. In the Bronsted-L...
aCa(OH)2+bSO2=c(CaOH)2SO3+dH2O Step 2: Create a System of Equations Create an equation for each element (Ca, O, H, S) where each term represents the number of atoms of the element in each reactant or product. Ca:1a +0b=2c +0dO:2a +2b =5c +1dH:2a +0b=2...
This marked difference is due to SO3 being a much stronger Lewis acid (pF(-) value of 7.83) than SO2 (pF(-) value of 3.99), thus forming a stronger S-N bond with the Lewis base N-3(-). The geometry of the free gaseous SO2N3- anion was calculated at the RHF, MP2, B3LYP, ...
spectroscopy and the unavailability of weak bases with overlapping log I values are the reasons for reduced reliance on acid-base indicators. Recently So~er et al. (Ref.9) have reported a new method of determination of the BH /B ratio using a dynamic NMR technique. The principle is based ...
