What are the control variables in a titration?
– Controlled Variables: The molarity of sodium hydroxide (1M), the type of vinegar (CH3OOH), room temperature, pressure, the addition of phenolphthalein indicator (3 drops), the volume of distilled water into the acid (50 mL).
What happens in a titration lab?
A titration is an experiment where a volume of a solution of known concentration is added to a volume of another solution in order to determine its concentration. Many titrations are acid-base neutralization reactions, though other types of titrations can also be performed.
What are independent and dependent variables of solution?
The independent variable is the variable being controlled in the problem, and the dependent variable is the variable that changes because of this control.
What is an independent variable and a dependent variable control or constant?
A dependent variable is the variable that changes in response to the changes in the independent variable. The dependent variable is the effect, output, or what happens during the experiment. A control/constant variable is the variable that is constant and unchanged throughout the course of the investigation.
What is the hypothesis of acid base titration?
Lab 7a: Acid-Base Titration Hypothesis: When an unknown concentration of hydrochloric acid (HCl) is titrated with a known volume of standardized sodium hydroxide (NaOH) solution, one can gather enough data to determine the concentration of the unknown analyte (HCl).
Which is the independent variable in a graph?
The independent variable belongs on the x-axis (horizontal line) of the graph and the dependent variable belongs on the y-axis (vertical line). The x and y axes cross at a point referred to as the origin, where the coordinates are (0,0).
What is the dependent and independent variable on a graph?
What is the aim of titration experiment?
The purpose of the titration is the detection of the equivalence point, the point at which chemically equivalent amounts of the reactants have been mixed. The amount of reactants that have been mixed at the equivalence point depends on the stoichiometry of the reaction.
