Tudor style roasting meat on a spit

Roasting is a cooking method that uses dry heat where hot air envelops the food, cooking it evenly on all sides with temperatures of at least 150 °C (~300 °F) from an open flame, oven, or other heat source. Roasting can enhance flavor through caramelization and Maillard browning on the surface of the food. Roasting uses indirect, diffused heat (as in an oven), and is suitable for slower cooking of meat in a larger, whole piece.[1] Meats and most root and bulb vegetables can be roasted. Any piece of meat, especially red meat, that has been cooked in this fashion is called a roast. Meats and vegetables prepared in this way are described as "roasted", e.g., roasted chicken or roasted squash.

Question:

How many litres of water must be added to 1 litre an aqueous solution of HCl with a pH of 1 to create an aqueous solution with pH of 2 ?

Solution:

pH = 1 ⇒  [H+] = 10–1 = 0.1 M

pH = 2 ⇒ [H+] = 10–2 = 0.01 M

for dilution of HCl,

M1V1 = M2V2

0.1 × 1 = 0.01 × V2

V2 = 10 L

Volume of water added = 10 – 1 = 9 litre
