LCSS: POTASSIUM
Note that the reactivity of potassium is generally related to its surface area and the cleanliness of the surface at hand; chunks of potassium are less reactive than the very dangerous dispersions and sands. Storage and Handling: Potassium should be handled in the laboratory using the "basic prudent practices" described in Chapter 5.C ...

Measurement for Surface Tension of Aqueous Inorganic Salt
Figure 5 shows the measured results for 1 mol/L sodium hydroxide solution at 35°C. Because the measurement period of platinum ring is long, the time interval between adjacent measurements is 30–40 min. The surface tension of 20°C sodium hydroxide solution is 59.36 mN/m, but the former two measured surface tensions of 35°C solution …

Potassium Chloride No. 3
Potassium chloride is the most widely used K fertilizer due to its relatively low cost and because it includes more K than most other sources...50 to 52% K (60 to 63% K 2 O) and 45 to 47% Cl-. Over 90% of global potash production is used for plant nutrition. Potassium chloride is often spread onto the soil surface prior to tillage and planting.
