side of the cell of the cell would provide more electrons‚ increasing the potential energy‚ which increases the voltage. Surface area of cathode and anode; if these two have different surface area‚ it should be more electrons could travel one way more than the other ways. To stop this affecting to my result‚ I will keep the surface areas of the anode and cathode the same. Another important thing in this experiment is length and width of salt bridge‚ the size of salt bridge that I use must be same

4002DFPHAR PHYSICAL PHARMACEUTICS Particle Size Analysis The study of particle dimensions is important in many areas of manufacture and technology. Many solid materials are at some point powder or granular in form e.g. foods (grain‚ flour‚ sugar)‚ ceramics and building materials (sand and cement). In pharmaceutical development and manufacture‚ particle size greatly influences physical properties such as powder flow‚ powder mixing‚ drug dissolution‚ deposition from inhaler devices and the stability

electrolysis the electric current enters and leaves the electrolyte by conducting rods called electrodes. The positive electrode is called the anode and the negative electrode is called the cathode. d) For electrolysis to occur the electrolyte must be in liquid form so that the ions are free to move. e) In electrolysis the negative ions move towards the anode. When they get there they lose electrons to form neutral atoms. The positive ions move towards the cathode. When they get there they gain electrons

The objective of this lab was to. First‚ we measured out 2.00g of granular zinc and 2.03g of iodine crystals and added them together into a boiling tube‚ which we labeled "R". After‚ we added a boiling chip into a large test tube labeled "P" and we also labeled an empty regular sized test tube with a "C". When we added 5mL of acetic acid to tube R‚ the solution turned red and was hot. After we add 30 drops of the red solution into tube C and continued to swirl tube R‚ the solution became

# Electrolytic refining: The copper from smelting is moulded into anodes‚ and the cathode is created from a pure sheet of copper. At the cathode a pure layer of copper is formed due to the oxidation that occurs at the anode and this decreases the cathode occurring. A sludge (muddy type of mixture) is created which form valuable metals such as gold and silver‚ which are less active than copper. The impurities which are left behind in the solution eg.iron are usually more active than the copper.

EXPERIMENT NO-1 AIM- To determine the frequency of A. C. mains by using an electric vibrator. APPARATUS- Electric vibrator‚ table lamp‚ pulley‚ weight box‚ fishing cord‚ a. c. source. THEORY- when a cord of mass per unit length m is connected to the vibrating rod of the vibrator and stretched with a tension T‚ the cord vibrators in segments. If the length of the cord is then adjusted until the nodes are clearly marked‚ the frequency of the stretched string is the same as of the vibrating rod which
