Answer:

The poisoned substance was mixed with arsenic-free zinc and sulfuric acid, resulting in arsine gas.

The gas was later ignited and decomposed into pure metallic arsenic. This test was highly sensitive and could detect even one-fiftieth of a milligram of arsenic. It was a remarkable discovery, since before that, arsenic was widely used as poison in enormous amounts of murders, impossible to detect and trace.

Hi, First, Let me explain line by line,

<h3>1} What allowed President Lincoln to issue the Emancipation Proclamation?</h3>

Ans:- Abraham Lincoln was forced to issue the Emancipation Proclamation on September 22, 1862 as a response to the heavy losses inflicted at the Battle of Antietam.

<h3>2} Did it end slavery in the United States? Why or why not?</h3>

Ans:- Yes. After the Union victory on May 1865. When the Thirteenth Amendment, December 1865 was issued, slavery was ended in the United States. But unfortunately, even till today, some people are hiring slaves without the knowledge of other people and the government.

<h3>3} How did the Proclamation impact the Civil War?</h3>

Ans:- Yes, absolutely. In the year January 1, 1863, Lincoln issued the Emancipation Proclamation. It also changed the aim of the war from preserving the Union to a fight for freedom of human rights.

With this proclamation, he tried to free all slaves in the Southern areas. But, sadly, the Emancipation Proclamation did not include slaves in the parts of the Confederacy under the high control of the Union.

<em>I </em><em>hope </em><em>this </em><em>will </em><em>be </em><em>a </em><em>good </em><em>opinion </em><em>from </em><em>my </em><em>side.</em>
