Not illustrated. 1921 edition. Excerpt: ...for this is the portion of the apparatus which must be kept entirely free from oxygen. Until the mercury-sealed stopcocks (Fig. 7b) were used, considerable difficulty was experienced from the amalgam flowing out of the legs of the apparatus on allowing it to stand several hour8. These stopcocks served their purpose admirably, and after they were used the work went along in a much more satisfactory manner. The samples of solutions taken for analysis were taken from the compartments L and K (Fig. 7) after the measurements had been made. This procedure was followed also with the tfcpe II oell. When the solutions were very dilute, however, they were not analysed. The concentration of the solutiSn was rtexff taken as that in the bottle containing the original supply of solution. This original supply was made up by weight from a more concentrated solution which had been previously analysed. V. Other ilpparatus. The Galvanometer. The characteristics of the galvanometer are as follows: (Leeds and Northrup, "High Sensitivity" Galvanometer Sensitivity, 13,012 megohms. Critical damping resistance, 55,000 ohms Resistance 760 chms Suspension 0.003) mm silver. This instrument was found well suited for use with cells of the high internal resistance which concentration oells using dilute solutions possess. The Potentiometer. This was a Type K, Leeds and Northrup instrument. The Standard Cell. The oell used was a Weston Normal Cell. This was frequently compared at the ska Wisconsin Standards Laboratory with Weston Normal oells which had been sent to the Bureau of Standards for comparison. The Working Battery. For all of the recorded measurements a new lead storage cell was used which was half discharged every month during use and then charged....show more
