Ionic bonds are considered to be strong chemical bonds,yet ions disociate in water. Explain this apparent contradiction.

The blood recieves an excess of carbon dioxide (CO[sub]2[/sub]) from metabolic activities which slightly lower blood pH,
yet the pH of the blood remains relatively constant. Explain how CO[sub]2[/sub] is buffered in the blood causing stabilisation of blood pH

Is buffering the same as neutralisation of acid/base solutions. please explain

Can salt be lost during evaporation because after evaporating H20 from NaCl i was left with 0.1g of salt but using the equation m=n×M there should of been 0.1255g of salt. How was the salt lost?

1. Correct each false statement: (10 points total) 1.1. Reactions that do not go to completion must have been performed carelessly.
(see section 10.1) 1.2.
If two reactant molecules collide, they will react. (section 10.4, figure 10.3)
1.3. Equilibrium constant expressions can be calculated from the initial amounts of reactants chosen for a trial. (§10.5)
1.4. If the Ksp for substance X is greater than the Ksp for substance Y, the molar solubility of X
must be greater than the molar solubility of Y. 1.5. The Ksp of a substance varies in the presence of a common ion.
