Permanganate

The purple looks like potassium permanganate, which is a strong oxidizer. ❋ Unknown (2010)

More accurate results are obtained by using a very dilute solution of potassium permanganate, which is decomposed by amyl alcohol much more rapidly than by ethyl alcohol. ❋ Various (N/A)

You can use soap or a chemical product such as permanganate of potash or cresol. ❋ Unknown (1976)

There may be added to the boiler, C, certain materials for purifying the acetic acid, such as permanganate of potassa or acetate of soda, so as to obtain an absolutely pure article. ❋ Various (N/A)

When hydrogen peroxide comes in contact with a catalyst, such as permanganate of potash, it breaks down into oxygen and water. ❋ Murray Leinster (1935)

The standard solution of "permanganate" is then run in, (not too quickly, and with constant shaking) until a permanent pink tinge is produced. ❋ Cornelius Beringer (1886)

Fifty c.c. of a solution of ferrous chloride, which required on titration 49.8 c.c. of "permanganate," required for re-titration (after subsequent reduction with stannous chloride) 50 c.c. of the permanganate solution. ❋ Cornelius Beringer (1886)

Another gram dissolved in acid and titrated with "permanganate" required 8.2 c.c. (standard = 0.4951). ❋ Cornelius Beringer (1886)

In one experiment 50 c.c. of the ferrous sulphate solution were titrated with "permanganate"; 49.3 c.c. of the last-mentioned solution were required. ❋ Cornelius Beringer (1886)

"permanganate" solution, and again titrate; about 30 c.c. of the "hypo" will be used. ❋ Cornelius Beringer (1886)

"permanganate," 48 c.c. of the latter were required. ❋ Cornelius Beringer (1886)

For example, 0.7560 gram of pyrolusite and 1.000 gram of iron were taken and treated as above; 13.9 c.c. of "permanganate" (standard 100 c.c. = ❋ Cornelius Beringer (1886)

But I saw him in the surgery five minutes afterwards, with Doctor Goodhue scarifying the wounds and injecting permanganate of potash. ❋ Unknown (2010)

For fear of poison, Sheldon had immediately scarified the wound and injected permanganate of potash; but in spite of the precaution the shoulder was swelling rapidly. ❋ Unknown (2010)

The rich kids shouted out "blackberries," "blackcurrant ice cream" and "potassium permanganate," a chemical used to clean fruits and vegetables. ❋ Geeta Anand (2011)

Others attempted the procedure themselves using rubber tubes, knitting needles, or potassium permanganate -- a corrosive substance that could end a pregnancy but all too often only caused bleeding, ulcers and burns. ❋ Unknown (2010)

The pits, lined with plastic, were used to dry the coca leaves, which were then mixed with solvents (kerosene, benzene, sulfuric acid) and base chemicals (magnesium permanganate, ammonia, cement carbonate). ❋ Louis Diaz (2010)
