What is the molarity of an aqueous phosphoric acid solution if 13.13 ml is completely neutralized by 19.64 ml of 0.09291 m naoh? collapse question part part 1 incorrect answer. did you write the correct molecular formula for phosphoric acid? write a balanced molecular equation for the reaction. be sure to include the appropriate phases for all reagents and products.

The molarity of this solution is 0.0695 M

Explanation:

Step 1: The balanced equation

H3PO4(aq) + 2NaOH(aq) → Na2HPO4(aq) + 2H2O(l)

Step 2: Given data

Volume of phosphoric acid (H3PO4) = 13.13 mL

volume of NaOH = 19.64 mL

Molarity of NaOH = 0.09291 M

Step 3: Calculate moles of NaOH

Number of moles = Molarity * volume

Number of moles = 0.09291 M * 19.64 mL *10^-3 L

Number of moles = 0.001825 moles

Step 4: Calculate moles of H3PO4

For 2 moles of NaOH there is 1 mole of H3PO4 consumed to produce 1 mole Na2HPO4

So for 0.001825 moles NaOH, there is consumed 0.001825/2 = 0.0009125 moles of H3PO4

Step 5: Calculate molarity of H3PO4

Molarity = number of moles / Volume

Molarity = 0.0009125 moles / (13.13 *10^-3L) = 0.0695 M

The molarity of this solution is 0.0695 M

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.

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )
