To determine the effects of the errors described on the concentration of potassium hydrogen phthalate, we need to understand the process of measuring concentration and how these errors can impact it.
1) Spilling some solid potassium hydrogen phthalate when transferring into the beaker:
In order to measure concentration accurately, we usually dissolve a known mass of the solute (in this case, potassium hydrogen phthalate) in a known volume of solvent (usually water). When some of the solid is spilled, the actual amount of solute added to the beaker decreases. As a result, the concentration of potassium hydrogen phthalate in the solution will be lower than the desired concentration.
To minimize the error, it is important to handle the solids carefully during transfer and confirm that all of the solid is transferred into the beaker without any loss. If some solid is spilled, it may be necessary to start the process again with a fresh sample to obtain accurate concentration results.
2) Not adding enough water to reach the mark:
The desired concentration is achieved by dissolving a known mass of the solute in a specific volume of solvent. If not enough water is added to bring the solution up to the proper volume, the final concentration of the potassium hydrogen phthalate will be higher than intended.
To rectify this error, you can add additional water to the beaker until the solution reaches the specified mark on the container. This will help dilute the solution and adjust the concentration to the desired level. It is important to be precise when measuring the volume of solvent to ensure accurate concentration results.
In summary, spilling solid potassium hydrogen phthalate during transfer and not adding enough water to reach the specified volume mark can both lead to errors in concentration measurement. It is crucial to follow proper laboratory techniques, handle the materials with care, and measure accurately to obtain reliable concentration values.
