To give Lewis structure of conjugate base of
Concept introduction:
• Lewis structures are the diagrams that show the bonding between the atoms of the molecules and existing lone pairs of electrons.
• Bonding electrons are those electrons which are shared between the atoms resulting in the formation of bond.
• Non-bonding electrons are the valence electrons of the atom which are not shared with another atom.

- A scientist is comparing two lakes. She finds that water samples from Lake X have a pH of 3.50 and water samples from Lake Y have a pH of 5.50. Therefore, it can be said that Lake X has a hydronium ion concentration that is times greater than Lake Y.arrow_forwardDefine and describe the properties of acids and bases with respect to hydrogen ions?arrow_forwardCalculate the hydrogen ion concentration in mol/L for solutions with the following pH values: (a) 2.42, (b) 11.21, (c) 6.96, (d) 15.00.arrow_forward
- The pH of a solution is 2.45. What is the molar concentration of hydronium ions in the solution? The answer should be to the proper number of significant digits.arrow_forwardBased on the Lewis structures of the reactants and product of the following equation, identify the Lewis acid and the Lewis base in it: CO, + OH → HCO, =c=0: + :0-H H-0- O: O Lewis acid: CO,; Lewis base: HCO, O Lewis acid: OH; Lewis base: CO, O Lewis acid: CO; Lewis base: OH-arrow_forwardFor the following acid-base reaction, (1) predict the products, showing both reactants and products complete Lewis structures and arrows showing electron flow; (2) label each structure with the lowing: Bronsted acid, Bronsted base, conjugate acid, conjugate base; (3) give a brief definition of a ronsted acid and Bronsted base; (4) predict the direction of the equilibrium and justify your answer.
