From the table of densities found in this experiment, iron has a density of 7. 85 g/cm3 and water has a density of 1. 0 g/ml. Iron is denser than water and will sink when placed in water. Explain how ships made from iron stay afloat using density principles.

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.
