OE Leucine- Aspartic Acid QUESTION 5 10 po In the laboratory, you have a beaker containing 100 milliliters (mL) of NaOH solution at pH 13. Into this beaker, you carefully pour 10 mL of HCI at pH-1. Which of the following statements best describes how the original contents of the beaker will be changed by this mixing? OA. At 25 °C, the product of [Ht] and [OH] will be 1012 after mixing. The concentrations of H+ and OH ions will become equal. The pH of the beaker's contents will increase. . . OD. The pH of the beaker's contents will decrease. O E. The concentration of Na+ ions will increase.Explanation / Answer
Look ...
The approach for solving consist 2 ways
1. That is numerically solve and get the answer and
2. Analysis of condition when HCl is mixed with NaOH...and that's easy and fast too ...
I will explain you using 2nd method that's easy to understand
When HCl is mixed in contain having NaOH then the proton ions coming from acid reacts with hydroxyl ions coming from base and form some moles of water ..now what we need to focus is ..the moles of hydroxyl ions are decreasing by time so relatively pH will decrease so
Answer is ....option..(C)..
