Want this question answered?
reaction takes place faster than of a solution that is less concentrated
As the temperature of the solution decreases, less sugar can be held in solution, so some of it goes out of solution and falls to the bottom of the container.
It move from the more concentrated place to the less concentrated place.
I don’t understand
The potato contains moisture that can act as a electrolytic solution. The electric voltage is created by placing to different metals, usually zinc and copper, into the potato. The potato only acts as a place for the reaction to take place. By itself, a potato has no electric value. If zinc is used the reaction follows: Zn → Zn2+ + 2 e-. Note the 2 free electrons produced, this causes the electric potential to develop between the poles of the potato battery. The total voltage produced depends on the metals used but usually peaks under 1v (~0.8v really).
first place a potato which is carved slightly inwards in the salt solution. it adsorbs the solution slowly and the level of the solution decreases.now place the pin at the potato
a) place in a concentrated salt solution.
It gets waterlogged. Really?

Those animal cells placed in pure water will swell but plant cells are restricted by their cells walls. If place in a solution high in sugar (or even salt), both cells will shrink in a process called crenation (shriveling).
As the temperature of the solution decreases, less sugar can be held in solution, so some of it goes out of solution and falls to the bottom of the container.

you would have to say something that involves adding a solute to make it concentrated. ex "A liquid with an added solute is consentrated".
in a place
no the potato comes from south America (Peru)
