Acids And Bases Essays - Chemistry, PH Indicators, Free Essays Acids And Bases What substances turned into Acids? & What substances turned into Bases? Hypothesis: Procedure: Pour about three milliliters of your sample in each of three test tubes. Pour the same amount on a watch glass. In the first test tube put in two drops of methyl orange and record the color. In the second test tube, put in two drops of bromothymol blue and record the color. In the third test tube, add two drops of phenothalein and record the color. Using the watch glass sample, touch the tips of a red and a blue litmus paper and record the colors. Then touch the tip of a piece of pH Paper and record the color and match the color to the chart and record the pH.

They react with metals to release hydrogen and have a pH less than 7. That is why litmus paper turns red. So anything that turned red in my chart was an acid. Bases are compounds made up of metallic elements or polyotomic ions combined with hydroxyl radicals. They are formed when some metals react with water and have a pH above 7. They turn litmus paper blue. So anything on my chart that is blue under litmus is Bases. So from my results it was very easy to clarify which substance was an acid and which one was a base.

The Border States of the Civil War

The Border States of the Civil War Border states was the term applied to a set of states which fell along the border between North and South during the Civil War. They were distinctive not merely for their geographical placement, but also because they had remained loyal to the Union even though slavery was legal within their borders. Another characteristic of a border state would be that a considerable anti-slavery element was present within the state which meant that, while the economy of the state would not have been heavily tied to the institution of slavery, the population of the state could present thorny political problems for the Lincoln administration. The border states are generally considered to have been Maryland, Delaware, Kentucky, and Missouri. By some reckonings, Virginia was considered to have been a border state although it did eventually secede from the Union to become part of the Confederacy. However, part of Virginia split away during the war to become the new state of West Virginia, which could then be considered a fifth border state. Political Difficulties and the Border States The border states posed particular political problems for President Abraham Lincoln as he tried to guide the nation during the Civil War. He often felt the need to move with caution on the issue of slavery, so as not to offend the citizens of the border states and that tended to annoy Lincolns own supporters in the North. The situation greatly feared by Lincoln, of course, was that being too aggressive in dealing with the issue of slavery might lead the pro-slavery elements in the border states to rebel and join the Confederacy which could be disastrous. If the border states joined the other slave  states in rebelling against the Union, it would have given the rebel army more manpower as well as more industrial capacity. Furthermore, if the state of Maryland joined the Confederacy, the national capital, Washington, D.C., would be put in the untenable position of being surrounded by states in armed rebellion to the government. Lincoln’s political skills managed to keep the border states within the Union, but he was often criticized for actions he took that some in the North interpreted as appeasement of border state slave owners. In the summer of 1862, for instance, he was condemned by many in the North for telling a group of African American visitors to the White House about a plan to send free blacks to colonies in Africa. When prodded by Horace Greeley, the legendary editor of the New York Tribune, to move faster to free slaves 1862, Lincoln responded with a famous and deeply controversial letter. The most prominent example of Lincoln paying heed to the particular circumstances of the border states would be in the Emancipation Proclamation, which stated that slaves in states in rebellion would be freed. Its notable that the slaves in the border states, and thereby part of the Union, were not set free by the proclamation. The ostensible reason for Lincoln excluding the slaves in the border states from the Emancipation Proclamation was that the proclamation was a wartime executive action and thus only applied to the slave states in rebellion- but it also avoided the issue of freeing slaves in border states which could, perhaps, have led some of the states to rebel and join the Confederacy.
