Question- how many grams of potassium hydrogen phthalate (KHP) will be required to completely neutralize 50 mL of 0.15 M NaOH solution?
Any help is greatly appreciated!
The water treatment plant uses filters that are 10 ft in diameter. If the filters are backwashed at 15 gpm/ft2 for 12 minutes, estimate the amount (gallons per wash) of wash water used.
A 0.484g sample of impure NH4Br is treated with 25.00mL of 0.2050 M NaOH and heated to drive off the NH3. The unreacted NaOH in the reaction mixture after heating required 9.95mL of 0.0525 M H2C2O4 to neutralize.
