Concentration of Ammonia in Window Cleaner Solution Design (D) Aim To determine the concentration of ammonia‚ NH3‚ in the commercial window cleaner solution Background Window cleaner contains ammonia‚ NH3‚ a weak base‚ which helps remove dirt from glassware. The concentration of ammonia in the window cleaner solution varies by brands. Titrating the window cleaner solution with an acid of known concentration allows us to calculate the concentration of the ammonia in that brand of window cleaner solution

Why does the colour leak out of beetroot? Procedure to investigate the effect of temperature Hypothesis- The higher the temperature while cooking the beetroot‚ the more pigments well leak out from the cell membrane‚ hence the absorbance would increase. My hypothesis was concluded by the facts that beetroot contains red pigments called betalians which are located in the cell vacuole. Normally the pigments cannot leak out; however cooking the beetroot allows the movement. This is because the cell

Chemicals : Crude diphenyl (3.0 g)‚ ethanol (20 mL)‚ decolourising charcoal (1.0 g)‚ boiling chips‚ ice Procedure : Crude diphenyl (3.0 g) is measured and obtained using a beaker and a laboratory electronic weigh. The crude diphenyl is then put into a quickfit flask‚ together with 2 to 3 pieces of boiling chips. Ethanol (5 mL) is measured using a measuring cylinder and poured into the flask. A vertical water condenser is fitted to the mouth

Daniel H. Perry Procedures of Measurement and Density of Sugar in Soda Introduction The main focus of this lab was to acquire a basic understanding of how to properly use measuring devices in order to determine properties of a liquid. These properties are volume‚ mass‚ and density. The following measurements were obtained in the lab: density of water‚ both density and concentration of aqueous sugar solutions‚ and density of various soft drinks with respect to sugar. Additional experience was
