Write a balanced chemical equation for the dissociation of calcium hydroxide: Calculate the pH of a 0.122 M solution of calcium hydroxide. Pay attention to the stoichiometry shown in your balanced equation above.
please help
please help!!
2. Write the balanced chemical equation for the neutralization of hypobromous acid with potassium hydroxide. Is the pH at the equivalence point above, below, or exactly 7? Explain. 3. Some pH meters are designed for a three-point calibration at pH 4, 7, and 10. Ours are only calibrated with a two-point procedure at 4 and 7 or 7 and 10. Which range would you expect we are calibrating them at for this experiment? Why? 4. (a)...

The Henderson-Hasselbalch (Buffer) Equation • The pH of the buffer solution is dependent more on pk, of the buffer than concentrations of acids and bases • As a rule, this equation is only useful if HA and A differ by less than a factor of 10 The K, of HCN is 4.9 x 10 What is the pH of a buffer solution that is 0.100 Min HCN and (0.200 M in KCN? Calculate the pH of a buffer which...

Please show all steps will leave a like for solving :)
Problem 2: The soil temperature in the upper layers of the earth's surface can vary with changes in atmospheric conditions. Before a cold front arrives, the temperature of the earth's soil near the surface is uniform at 15°C. The cold front stays for 2 days keeping the surface temperature constant at -12°C. The soil properties are: k=0.5W/m.°C and a = 0.15x10 mº/s. What is the temperature...

I need help solving this problem, thank you.
Need help solving the 3 parts of the problem. Thanks.
Calculate the pH for a 0.010 M solution of 4-Methylphenol. Derive the most rigorous equation for solving this problem. However, simplify and show the equation that you actually use to calculate the pH. This equation must be a polynomial of order 2 (quadratic) or less for credit.
