How to remove a specific color in an image in Photoshop?

Question 1

I am not an expert photoshop user but have been trying to use more of it in what I currently do.

I have a black and white image from
which I am trying to remove all the white.

I cannot use the magic wand/delete
because the white is in literally hundreds of places and in some cases very tiny.

Is there a method to strip the white off, leaving just the black?

Thanks in advance for your help.

Question 2

Indeed you should perform right selection.

Select->Color Range and click on the spot colored with color you want to select – you will see the change on the preview screen.

Also, you can choose the color from sampled colors drop down menu

Fuzziness should be set to 0.

If you press SHIFT while selecting (you can also click Shift and drag of the image) it will select all the spots with the same color….

After selection was made you can perform on it any action you want…
