Answer:
You will need 10 mL of stock Tris, 15mL of stock NaCl and enough water to bring the total volume to 500 mL.
Explanation:
<u>The desired buffer contains:</u>
- Total volume of 500 mL
- Tris 30mM
- NaCl 150mM
<u>The stock solutions are:</u>
- 1.5M = 1500mM Tris
- 5M = 5000mM NaCl
We can use the formula C1V1=C2V2 to calculate the volume of each stock required to prepare the buffer.
<h2>
<u>Tris</u></h2>
- C1= 1500 mM
- V1=?
- C2= 30mM
- V2= 500 mL
1500 mM x V1 = 30mM x 500 mL
V1 = (30mM x 500 mL) / 1500 mM
V1 = 10 mL
<h2>
<u>NaCl</u></h2>
- C1= 5000 mM
- V1=?
- C2= 150 mM
- v2= 500 mL
5000 mM x V1 = 150mM x 500 mL
V1 = (150 mM x 500 mL) / 5000 mM
V1 = 15 mL
You will need 10 mL of stock Tris, 15mL of stock NaCl and enough water to bring the total volume to 500 mL.
Answer:
Liquid ammonia is liquefied ammonia and is basic in nature. It dissolves in water to give ammonium hydroxide which ionizes to give hydroxyl ions. Therefore it turns red litmus blue and phenolphthalein solution pink.
Answer:
exocytosis is the process described above
