Question

Volume of the buffer were 0.270 m in NH₃ and 0.400 m in NH₄Br , what mass of HCL could be handled before the ph falls below 9.00?

Answer 1

To determine the mass of HCl that can be handled before the pH falls below 9.00, we need to consider the reaction between NH₃ and HCl in the buffer solution. The balanced chemical equation for this reaction is: NH₃ + HCl → NH₄Cl. From the equation, we can see that 1 mol of HCl reacts with 1 mol of NH₃ to form 1 mol of NH₄Cl.

Step-by-step explanation:

To determine the mass of HCl that can be handled before the pH falls below 9.00, we need to consider the reaction between NH₃ and HCl in the buffer solution. The balanced chemical equation for this reaction is:

NH₃ + HCl → NH₄Cl

From the equation, we can see that 1 mol of HCl reacts with 1 mol of NH₃ to form 1 mol of NH₄Cl. To find the mass of HCl that can be handled, we need to calculate the number of moles of NH₃ in the buffer solution, then use the stoichiometry of the reaction to determine the mass of HCl.
