A1.0-l buffer solution initially contains 0.30 mol of nh3 and 0.30 mol of nh4cl what mass of the correct reagent should you add?

To find the mass of reagent to be added in the reaction, we need to determine the pH of the buffer. Using the following equation

pH= pKa + log ([NH3] / [NH4+])
     = 9.26 + LOG ( 0.3 / 0.3)
     = 9.26

[h+]= 5.5x10^-10 M, you need to increase that concentration for a ph of 8.6, [H+] needs to be 2.51x10^-9M

2.51x10^-9 moles - 5.5x10^10 moles = 1.96x10^-9 moles 

1.96x10^-9 x 36.45g/mole = 7.14x10^-8 g

So the mass of HCI that you should add to the reaction is 7.14x10^-8 g

Wow that a lot of text for my tiny so i no wanna answer

Answerd. may include all of these are many definitions of bases: the  brønsted-lowry definition of acids and bases says that bases are proton acceptors.the arrhenius definition of acids and bases says that bases increase [oh⁻] in solution (thereby producing oh⁻ ions)the lewis definition of acids and bases says that bases donate electron pairs.therefore, the sensible answer is that a base may include all of the described characteristics.
