Step 2

Since, 2 moles of HNO3 reacts with 1 mole of Ca(OH)2.

Therefore, 1 moles of HNO3 reacts with 0.5 mole of Ca(OH)2.

To calculate the amount of solid Ca(OH)2 required to neutralise 17.4 ml of a 1.30 M HNO3, we will first calculate the no. of moles of Ca(OH)2  and HNO3.

Step 3

Now as per the balanced equation, I mole of HNO3 reacts with 0.5 mole of Ca(OH)2.

Hence, 0.02262 mol of HNO3 reacts with 0.5 mole of Ca(OH)2 gi...
