In a redox titration 12.50 mL of 0.0800 mol/L K2Cr2O7 (aq) was used in acidic solution to oxidize Sn2 (aq) ions to Sn4 (aq) ions. The volume of K2Cr2O7 (aq) used was just sufficient to oxidize all the Sn2 (aq) in 10.0 mL of the solution. Calculate the concentration of the Sn2 (aq) ions in the solution according to the following unbalanced equation. Cr2O72- (aq) + Sn2+ (aq) → Snº+(aq) + Cr3+(aq)

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.
