The concentration of fluoride, lead, nit...

The concentration of fluoride, lead, nitrate and iron in a water sample from an underground lake was found to be 1000 ppb, 40 ppb, 100 ppm and 0.2 ppm respectively. The water is unsuitable for drinking due to high concentration of-

A

fluoride

B

lead

C

nitrate

D

iron

Text Solution

Verified by Experts

In the sample of water, concentration of fluoride, lead and iron are in permissible limit but the concentration of nitrate ion is much higher than its permissible limit. Thus the water is not suitable for drinking

Ethyl acetate is formed by the reaction between ethanol and acetic acid and the equilibrium is represented as: CH_(3)COOH(l)+C_(2)H_(5)OH(l)hArr CH_(3)COOC_(2)H_(5)(l)+H_(2)O(l) (1) Write the concentration ration (reaction, quotient), Q_(c) , for this reaction (note: Water is not in excess and is not a solvent in this reaction). (2) At 293K, if one starts with 1.00 mol of acetic acid and 0.18 mol of ethanol, there is 0.171 mol of ethyl acetate in the final equilibrium mixture. calculate the equilibrium constant.
