Question

Luigi Galvani discovered that some chemical reactions that made new
substances also produced an electric current. Later Alessandro Volta invented a
battery that could be used to make an electric current
Humphrey Davy reasoned that as an electric current is produced when some
new substances are made then perhaps an electric current could be used to break
down a substance into its elements.
Davy made a battery, passed an electric current through water and broke it up into
the two elements from which it is formed. He then investigated with a substance
called potash, using an electric current to see if he could find the elements it was
made from. He mixed the potash with a large amount of water but it did not break
up.
He continued his investigation by heating some solid potash on a platinum
spoon and tried again but it did not work. Next, he added a small amount of
water to the potash, just to make it moist, and this time the electric current passed
through it, broke it up and revealed that the potash contained a new element,
potassium
a) What was the evidence from Galvani's investigation that Davy used in his
own?
b) What invention from Volta's work did Davy use in his own work?
c) In the text above underline the part that shows Davy's creative thought.d) What are the two elements that join together to produce water?
e) What do
you
think Davy's prediction was that drove him to investigate
potash?
f) Scientists have to be persistent in their investigations. Mark two sections
of text on the previous page to highlight two activities that show Davy's
persistence in finding an answer to his prediction​
