32 Memahami 7. Acid and bases S Pelengkap F
32 Table 32 shows the information of the two solutions:Jadual 32 menunjukkan maklumat tentang dua larutan.:
Which of the following statement are true about two solutions Penyataan manakah benar tentang dua larutan itu
I The concentration of OH- ion in sodium hydroxide solution is lower than in ammonium hydroxide solution. Larutan natrium hidroksida mempunyai kepekatan ion OH- yang lebih rendah daripada larutan ammonium hidroksida.
II The pH value of sodium hydroxide solution is higher than the pH value of ammonium hydroxide solution. Larutan natrium hidroksida mempunyai nilai pH yang lebih tinggi berbanding larutan ammonium hidroksida.
III The degree of dissociation of sodium hydroxide solution in water is lower than the degree of dissociation of ammonium hydroxide solution in water.Darjah penceraian larutan natrium hidroksida dalam air adalah lebih rendah berbanding darjah penceraian larutan ammonium hidroksida dalam air.
IV Ammonium hydroxide solution is a weak alkali while sodium hydroxide solution is a strong alkali.Larutan ammonium hidroksida adalah alkali adalah lemah manakala arutan natrium hidroksida adalah alkali kuat.
A I and III dan II
B I and III I dan III
C II dan IVII dan IV
D III and IV III dan IV
0.2 mol dm-3 sodium hydroxide solution pH=13 0.2 mol dm-3 larutan natrium hidroksida
0.2 mol dm-3 ammonium hydroxide solution pH= 9 0.2 mol dm-3 larutan ammonium hidroksida
