Explanation:
.A solution that serves as a pH indicator may be made using red cabbage, which is frequently available in homes. In essence, the color of the cabbage depends on the acidity of the solution and a pigment molecule called flavin or anthocyanin.
To determine whether a material is an acid or a base, red cabbage indicator is a purple-colored solution
Vinegar is an acid and its pH value is less than 7 and hence
Red color is produced
Baking soda is base and its pH value is greater than 7 and between 8-9
and the color produced is sky blue
Bleach is the green which is also a basic and because the pH value is 10-11
Householder cleaner is having pH 11-13 which is basic and hence the yellow is the color of household cleaner .
A basic solution goes away from being basic and toward the center of the pH scale when an acid is introduced. The base is "neutralized" in this manner.

Answer:
1. 7.256g of NaCl
2. 47.33g of Cl2
Explanation:
2 moles of Na reacts to produce 2 moles of NaCl
8 moles of Na will still produce 8 moles of NaCl
Mass of NaCl = molar mass of Nacl/moles of Nacl
=58.5/8
=7.256g of NaCl
From the equation, 2 moles of Na reacts with 1 mole of Cl2
3/2 moles of Cl2 will react with 3 moles of Na
Mass of Cl2 = 71/1.5
=47.33g of Cl2
