Question 1 1 pts A buffer can be prepared by mixing two solutions. Determine if each of the following mixtures will result in a buffer solution or not. 1) Mixing 100.0 mL of 0.1 M HCl with 100.0 mL of 0.1 M NaOH No, it will not result in a buffel 2) Mixing 100.0 mL of 0.1 MCH3COOH with 100.0 mL of 0.05 Mmol CH3COONa Yes, it will result in a buffer so 3) Mixing 100.0 mL of 0.1 MNH: With 100,0 mL of 0.1 M NHACI Yes, it will result in a buffer so 3565 4) Mixing 100.0 mL of 0.1 MNH, with 100.0 mL of 0.05 MHNO No, it will not result in a buffel - 5) Mixing 100.0 mL of 0.1 MNH) with 100.0 mL of Ol1 MENOS [Select ] Next

Answer 1

Buffer solution is a solution which resists the small Change in pH. Buffers are of two types: (1) Acidic buffer: I) is a mixture of weak acid solution and its salt (6) Bd Basic buffer. It is the solilion of werk base and its sall (1) Hel strong and can't foom NAOH - String base I buffer (2) CH₃COOH weak and I will form CH₃COONa salt of weak acidy acidic bouffer (3) NH - weak base I will form Nhill - sall of NH₃ I basic lauffer (4) OIM NH₂ weak base 0.05 M. HNO - strong acid In this case, a very less amount of HNO₃ har been taken as compared to NH₃. Thus, some amount of

NH3 will react with HNO to give NHINO (salt of NH₂). Thus the and some amount of NH₃ will remain as such. Thus, solution will finally contain NH₃ & WHY NO, and hence will act as buffer (s) 0.1M NH₂ - Weale bax 0.1M HNO - Strong acid Here equal amount of two have been taken, Thus, NH will completely react with HNO₂. So, it will not act as buffer ♡ Like of understood, comment for more help.
