Water is not a good pH buffer.
No, it is a poor buffer.
Potato contains a lot of fibres which help in a great conductivity that's why it is used to make battery.
because it makes you fat

If it is potato salad that is made with mayonnaise, then it spoils when not in the refrigerator and makes people sick. Not a good picnic food if you are out in the sun where it can get hot before eating.

if you mean your finger nail then a nail buffer just makes your nails look nice and shiny
Mr Rahani is a good potato ! ;) :)
The buffer capacity increases as the concentration of the buffer solution increases and is a maximum when the pH is equal to the same value as the pKa of the weak acid in the buffer. A buffer solution is a good buffer in the pH range that is + or - 1 pH unit of the pKa. Beyond that, buffering capacity is minimal.
A buffer is used to resist the change in pH when acid or alkali is added to a solution. This makes it a stable environment, eg. for enzymes. The buffer stops the pH of the solution changing too drastically.
the potato is good to eat
