In the NaCl solution, the concentrations are: [Na+] = 1.00 × 10−2 mol/L and [Cl−] = 1.00 × 10−2 mol/L When 1 liter of one of the ...
Some reactions are said to go to completion because the equilibrium condition is achieved when practically all the reactants hav ...
Looking at specific examples, we find that in some cases endothermic reactions occur when the products provide greater randomnes ...
TIP Know these relationships. This drive to achieve a minimum of free energy may be interpreted as the driving force of a chemic ...

example. Hydrochloric is a strong acid. It gives up protons readily. It follows that the Cl–ion has little tendency to attract a ...
The acid–base systems are summarized below. Type Acid Base Arrhenius H + or H 3 O+ producer OH – producer Brønsted-Lowry proton ...
(^) pH = −log [10−1] 3rd step. The logarithm of 10−1 is −1 so pH = −(−1) 4th step. The pH then is = 1. Because water has a norma ...
REMEMBER pH + pOH = 14 Sample Problem What is the pOH of a solution whose pH is 3.0? Substituting 3.0 for pH in the expression p ...
at the end point by about 6 units. For titrations of strong acids and weak bases, we need an indicator, such as methyl orange, t ...
H+(aq) + OH−(aq) → H 2 O(l) until all the OH− was neutralized; then the excess H+ caused the litmus paper to change color. To so ...
Example 1 Find the concentration of acetic acid in vinegar if 21.6 milliliters of 0.20 M NaOH is needed to titrate a 25-millilit ...
Substituting the HCl information in the equation, we have Since 1 mol of HCl neutralizes 1 mol of NaOH, 0.001 mol of NaOH must b ...
