The names and chemical formulae of some chemical compounds are written in the first two columns of the table below. Each compound is soluble in water. Imagine that a few tenths of a mole of each compound is dissolved in a liter of water. Then, write down in the third column of the table the chemical formula of the major chemical species that will be present in this solution. For example, you know water itself will be present, so you can begin each list with the chemical formula for water (H,O). Note: "major" chemical species are those present in concentrations greater than 10 -6 mol/L. major species present when dissolved in water compound formula 0.0. potassium cyanide KCN potassium nitrate KNO, nickel(II) chloride NiCl,

The freezing point of water is 0.00 °C at 1 atmosphere. How many grams of potassium nitrate (101.1 g/mol), must be dissolved in 201.0 grams of water to reduce the freezing point by 0.400 °C? Refer to the table for the necessary boiling or freezing point constant.

What will be the result of increasing the temperature on the rate of dissolution when dissolving salt in water

is the weight of a pure substance which is chemically equivalent to or reacts with a fixed volume of the solution (usually to 1mL). Mole Molarity Titer Normality
