SnO_(2) form a positively charged colloidal sol in the acidic medium and negatively charged sol in the basic medium. Explain.

SnO_2 forms a positively charged colloidal sol in the acidic medium and negatively charged sol in the basic medium. Explain.

SnO_2 forms a positively charged colloidal solution in acidic medium and a negetively charged colloidal solution in basic medium. Explain.

Give one example of positively charged sol and one example of negatively charged sol.

Give one example of positively charged sol and one example of negatively charged sol.

The sol given below with negatively charged colloidal particles is :

Why 'SnO2' forms a positively charged sol in solutions with 'pH 7'

What will happen if equimolar solution of positively and negatively charged colloidal sols be mixed ?
