In an experiment, 5 cm3 of 1.0 mol/dm3 NaOH solution is gradually added to 10 cm3 of 1.0 mol/dm3 HCl solution containing methyl orange indicator.
Which of the following changes will occur in the mixture?
A pH of the resultant solution increases.
BThe methyl orange indicator changes colour from red to yellow.
CNumber of moles of water decreases and beaker gets warmed up.
DA precipitate is formed.
the solution is acidic hence it will have PH in decrees form so the answer should be option 2
