يعنى التعليق اللى قولته على الجمله الاخيره ممكن يكون صح ولا ايه حضرتك؟!:confused:

Dear All, the time has come to answer the quiz

Try to figure out the errors in these sentences.. if present

a-In Guignard paper test, sodium picrate is oxidized by hydrocyanic acid to sodium picramate which has a red color

Reduced; as HCN reduces nitro group (NO2) of sodium picrate which has yellow color converting it to amino group (NH2) >> sodium picramate (sodium isopurpurate) which has brick red color

b-Nux vomica seed is very horny due to its very thick cellulosic walls of endosperm and sclenenchymatous epidermis

hemicellulosic; note: horny means hard

c-Linseed T.S shows positive results with both Alkana Tincture and Sudan III

This statement is true as both alkana tincture and sudan III give positive results with fixed oils but only sudan III gives positive results with volatile oils, also we can differenciate both by pressing the powder between two filter papers

d-Type of ovule of Nux vomica seed is anatropous as it shows raphe

atropous ..................no raphe; there is a slight line that appears on the surface of the seed but this is due to crossing of hairs of the testa

e-Strychnine is very toxic in very high doses and causes spasms

low; as if a compound has high toxicity so it is toxic in a very low dose (here, strychnine lethal concentration is about 3.2 mg) while if a compound is toxic in very high doses (very high lethal concentration) so this compound is considered safe

Best answers: Pharmcist_girl, dr_ amoona, Huda and dr asma

Thanks Pharmcist_girl again for providing us with information about toxicity of strychnine

Thanks for all who participated

Wishing you all the best of luck
