What new weapons were used in World War I?

Military technology of the time included important innovations in machine guns, grenades, and artillery, along with essentially new weapons such as submarines, poison gas, warplanes and tanks.

Does urine negate chlorine gas?

Chlorine reacts with urine to form a host of potentially toxic compounds called disinfection byproducts. These can include anything from the chloramines that give well-used pools the aforementioned odor, to cyanogen chloride, which is classified as a chemical warfare agent.

What are the types of chemical weapons?

Types of Chemical Weapon Agents

• Nerve agents (such as sarin, soman, cyclohexylsarin, tabun, VX)
• Vesicating or blistering agents (such as mustards, lewisite)

How did chamberpots help families collect their urine?

What makes leather soft when soaked in urine?

Urine-soaked leather makes it soft: Prior to the ability to synthesize chemicals in the lab, urine was a quick and rich source of urea, a nitrogen-based organic compound. When stored for long periods of time, urea decays into ammonia. Ammonia in water acts as a caustic but weak base.

What kind of manure was used to make saltpetre?

As detailed in the manual Instructions for the Manufacture of Saltpetre, written by physician and geologist Joseph LeConte in 1862, a person hoping to make gunpowder quickly would need “a good supply of thoroughly rotted manure of the richest kind” which is then mixed with ash, leaves and straw in a pit.

How are nitrates used in the making of gunpowder?

Different regions of the world had their own recipes for gunpowder, but the scientific principle at work is the same: Ammonia from stagnant pee reacts with oxygen to form nitrates. These nitrates–negatively charged nitrogen-bearing ions–then search for positively charged metal ions in the pee-poo-ash slurry to bind with.
