Recall that the formula for ΔHrxn = [(-Ccal)(moles of limiting reactant)/(ΔT)] If the actual concentration of the sodium hydroxide used in the calibration part of the experiment was lower than the stated value, will the value of Ccal increase, decrease, or remain the same? Please explain.  How about if the actual concentration of the sodium hydroxide used in the calibration part of the experiment was lower than the stated value. However, the NaOH solution used in the determination of ΔHrxn was of the correct concentration.  Will the magnitue of ΔHrxn increase, decrease, or remain the same? Please explain.

Solutions

Solutions can be considered as homogeneous mixtures which contain two or more than two chemical substances. The chemical substance which is the greater part is defined as solvent. And the chemical substance that is dissolved in a solvent is referred to as solute. Solution chemistry plays an important role in chemistry since it supports many commercial applications of solutions.
