<u>Answer:</u> The correct answer is
<u>Explanation:</u>
A base is defined as the substance which looses hydroxide ions when dissolved in water.
An acid is defined as the substance which looses hydrogen ions when dissolved in water.
From the given options:
AgO and NaCl are the salts. Both are ionic salts which are formed from the reaction of a metal and an non-metal.
HF is an acid because it released ions when dissolved in water. The equation for the ionization of HF follows:
is a base because it released
ions when dissolved in water. The equation for the ionization of
follows:
Hence, the correct answer is
Answer: The process is diffusion.
Explanation:
a dark liquid will have the highest concentration of dark purple atoms/molecules so it gives a concentrated colour.
when water is added to it, the colourless water molecules fill up the gaps between the purple particles and so their colour fades and becomes lighter and lighter as we add more water. see the image attached where imagine the red particles are water and the blue particles are purple particles. thats why the colour fades.
