PURE SILVER WIRE

Pure metal wire ideal for seeding solutions and a number of other experiments. Also can be used for making jewelry. Includes Certificate that guarantees assayed purity of at least 99.99%. About 36-inches long; 1 ounce; 30 gauge wire.

FULL RANGE PH TEST PAPERS

Indispensable for lab work! Simply dip paper wick into liquid or wet surface to measure acidity or alkalinity level. Full range from pH 1-14. Readings in red hues (1-6) indicate acids. For instance, strong acids like sulfuric and nitric test around 1 (red), while weak acids like acetic and carbonic test around 6 (yellow). A pH of 7 (green) is neutral (distilled water). Weak bases like calcium hydroxide test around 8 (blue), while strong bases like sodium hydroxide test around 14 (purple). Also indicates relative hydrogen ion concentration (increases with acidity). Includes full color chart. 100 test strips. Item #SK135. $4.95
