Answer:
21) -acidic
Carbon dioxide is slightly soluble in water (1.79 volumes per volume at 0 °C and atmospheric pressure, larger amounts at higher pressures), forming a weakly acidic solution. This solution contains the dibasic acid called carbonic acid (H2CO3).
22) -solid solution
Because bronze consists mainly of copper, copper is the solvent and tin is the solute. The two metals are combined in a hot, molten state, but they form a solid solution at room temperature
23) -solution
Mixed together, lemon juice, water, and sugar form a solution. A solution is a mixture in which the different kinds of matter are spread out evenly. In lemonade, water is called the solvent.
24) -homogeneous mixture
Because the composition of the solution is uniform throughout, it is a homogeneous mixture. A Orange juice contains particles of solid (pulp) as well as liquid; it is not chemically pure. B Because its composition is not uniform throughout, orange juice is a heterogeneous mixture.
25) -colloidal solution
Blood is a colloidal solution of an albuminoid substance. The styptic action of alum and ferric chloride solution is due to coagulation of blood forming a clot which stops further bleeding.
