1. Calculate the pH and pOH of an 0.5 mol/L NH3∙Н2О (aqueous solution). Take in to account that NH3∙Н2О is a weak electrolyte with Кb(NH3∙Н2О) = 1.8·10-5 mol/L.

it is important to conserve water because there is very limited amount of freshwater here on earth and if we are not smart about how we use it we will only be runnning out of our supply faster than neccessarry.

water and alcohols have similar properties because water molecules contain hydroxyl groups that can form hydrogen bonds with other water molecules and with alcohol molecules, and likewise alcohol molecules can form hydrogen bonds with other alcohol molecules as well as with water.
