Water blank

What is a water blank?

I am doing some research and I am suppose to prepare a solution. I should mix 10g of soil with 95ml of water blank in order to create a soil suspension.

My problem is I am not English and I have no idea what a water blank is. I have a feeling the type of water is pretty important here though. (can't find what it is on the internet).

Help please. A simple definition/description will do.

Blank experiment is in the case of without the samples, using quantitative analysis of samples of the same measuring method and the steps, the results as the blank value, deducted from the results of the analysis of the sample. It is a common method in chemistry experiment, it can reduce the experimental error.
Water blank is a kind of blank experiment, I guess!
