Answer:
Latitude:
Longitude:
Explanation:
Lets begin by explaining the meaning of latitude and longitude as geogrephical coordinates:
Latitude is the angular distance between the equatorial line, and a specific point on the Earth. It is measured in degrees and is represented according to the hemisphere in which the point is located, which can be north or south latitude.
In this sense latitude refers to the equatorial line that divides the Earth in two hemispheres (North and South).
Longitude represents the specific east–west position of a point on the Earth's surface, being longitude the prime meridian or Greenwich meridian.
So, according to the figure, where the model of the Earth is divided by latitude lines separated by and the longitude lines separated by
; we only have to count the lines from the equator to the line where the point A is, and count the lines fromo the Prime meridian to the line where point A is located.
Hence, point A location is:
Latitude:
Longitude:
The solution shall contain only (and water) at the equivalence point. Both potassium hydroxide and nitric acid exist as strong electrolytes. As a result,
, the salt derived from a reaction between the two species would undergo hydrolysis of a negligible extent. This neutralization reaction therefore be neutral at the equilibrium point.
The question states that the solution is "titrated with a ... nitric acid solution" indicating that is added to the initially-basic solution. PH value of the solution would keep decreasing as the volume of the acid added increases. The final solution would be acidic as it contains not only water and
, but some
as well. Bromothymol blue would therefore demonstrates a yellow color, the color it present in an acidic solution, at the end of the titration.
