Answer :
Final answer:
The pH of a buffer solution prepared with 2.00g of NH4Cl and 2.00g of NH4OH can be calculated using the formula pH = 14.00 - pOH, where pOH is the negative logarithm of the hydroxide ion concentration of the solution.
Explanation:
The subject of your question pertains to calculating the pH of a buffer solution. In your case, you added 2.00g of NH4Cl and 2.00g of NH4OH to the solution. The pH of a solution can be calculated using the formula pH = 14.00 - pOH. In this context, 'pOH' refers to the negative logarithm (base 10) of the hydroxide ion concentration ([OH-]). Therefore, to find the pH of the solution you first need to calculate the pOH and then subtract it from 14. For instance, if your solution had a [OH-] = 9.7 × 10-4, you would calculate pOH = log(9.7 × 10-4) and then subtract that from 14 to find the pH. If you follow these steps for your solution, you should be able to determine the pH.
