Vedclass · Answer

(C) Colloidal particles in a sol carry a specific type of electrical charge. Positively charged sols include: $TiO_2$,$CdS$,$Fe_2O_3$. Negatively charged sols include: blood,$Cu$,$Ag$,Clay,$SiO_2$. Wait,let us re-evaluate the classification: Positively charged sols: $TiO_2$,$Fe_2O_3$. Negatively charged sols: blood,$CdS$,$Cu$,$Ag$,Clay,$SiO_2$. Actually,standard classification is: Positively charged: $TiO_2$,$Fe_2O_3$. Negatively charged: blood,$CdS$,$Cu$,$Ag$,Clay,$SiO_2$. Total positively charged = $2$. Total negatively charged = $6$. Therefore,the correct option is $C$.

The number of positively and negatively charged sols respectively in the following are $TiO_2$,blood,$CdS$,$Cu$,$Ag$,Clay,$SiO_2$,$Fe_2O_3$.
