actually, no. H2O is not acidic because it is covelent, not ionic like H2SO4 (Sulfiric acid). when H2O acidifies it makes a H3O group and a OH (Hydroxide) group, in an equilibrium state. The H3O is actually what is acidic and the OH is basic.
My face when people say things about chemistry and they are wrong:
btw: You can remove the carbon dioxide in the water by reducing pressure.
I bring my air tight container, put my class of distilled water in it, and then attach a vacuum machine that takes out as much air as it can to about 3% volume of air has removed, and at a certain pressure does the gas boil out.
and after taking 100 grams of distilled water saturated with Carbon Dioxide at about .5 to 1 degree Celsius, I attach it to the vacuum and it boils out and it turns out my original 100g of distilled water is about 98g now and it lost 2 full grams of carbon dioxide.
