Answer:
B. Acid + base = salt + water
Explanation:
In accordance to the proposal of a scientist called Svante Arrhenius, an acid is a substance that increases the H+ concentration of a solution by dissociating into it while the base increases the OH- concentration of a solution by dissociating into it. Furthermore, Arrhenius stated that this two ions combine in an aqueous solution to give water.
Hence, Arrhenius acid-base reaction is the combination of an acid and base to produce salt and water as products. That is; Acid + base = salt + water.
Answer:
The correct options are A, and C.
Explanation:
Osmosis: It is defined as the movement of solvent with the help of selectively semipermeable membrane into a region of where high solute concentration is present to equalize the concentration of solute on the both compartments.
Reverse osmosis: It is defined as the movement of the high concentration solvent is forced onto the lighter concentration side with the help of mechanical pressure.
