Let’s Make Salt Purpose: Could NaCl be made using NaHCO3‚ hydrochloric acid‚ and a boiling chip? Hypothesis: If I combined NaHCO3‚ hydrochloric acid‚ and a boiling chip I think it will form NaCl because when you balance the equation it makes a new chemical reaction. Materials needed: test tube cleaner‚ test tube‚ test tube tongs‚ hot plate‚ a scale‚ graduated cylinder‚ water‚ goggles‚ fire retardant glove‚ beaker‚ test tube holder‚ a scoopula‚ hydrochloric acid‚ sodium bicarbonate‚ soap‚ pipette

Gravimetric Analysis of CA2+ as CaC2O4.H2O Introduction Weight determination represents one of the most accurate and precise form of measurement carried out in lab analysis. Thus‚ gravimetric analysis provides a great assay of a variety of analytes. Mixtures of compounds in difference phases provide us with one of the simplest methods of separation and mass explorations. Separating a solid mass from a liquid involves the commonplace

Acid Base Titration Purpose: The purpose is to calculate the molarity of a NaOH solution by titrating the base with 5mL of standard HCl solution in each trial. By adding the base with unknown molarity to the acid with 0.10M the molarity of NaOH can be calculated. The base‚ NaOH‚ helps bring the pH of the acid‚ HCl‚ closer to seven‚ which neutralizes it. When using the buret the amount of NaOH used is able to be determined. Then by writing a balanced chemical equation and using the titration
