Answer :
Answer
The following acids and alkalis into the order of most to the least dangerous are:
Alkali 1 - Conc(M) - 2M; pH 14 > Acid 2 - Conc(M) - 5M; pH 6 > Alkali 2 - Conc(M) - 2M; pH 8 > Acid 1 - Conc(M) - 0.5M; pH 6
The risks they would pose are: On contact with skin and other body tissue the acids and alkali can cause chemical burns and even burn through flesh. In addition to this, many are also toxic.
Explanation
On a pH scale acidity ranges from 1 to 7 and it increases by moving down from 7 to 1 while basicity/alkalinity ranges from 7 to 14 which increases by moving up from 7 to 14. So, the higher the pH value weak is the acid while the higher the pH value for a base means stronger the base.
Similarly, the higher the concentration of acids and bases, the stronger they are.
Therefore, the following acids and alkalis into the order of most to the least dangerous are:
Alkali 1 - Conc(M) - 2M; pH 14 > Acid 2 - Conc(M) - 5M; pH 6 > Alkali 2 - Conc(M) - 2M; pH 8 > Acid 1 - Conc(M) - 0.5M; pH 6
The risks they would pose are: On contact with skin and other body tissue the acids and alkali can cause chemical burns and even burn through flesh. In addition to this, many are also toxic
