No, sodium hydroxide is a strong base so its pH must be higher than 7.
-log(10^-4 M) = 4 14 - 4 = 10 pH
More than 7
precipitated Fe(OH)3 = ferric hydroxide or Fe(OH)4-(aq) = ferrate anion in solution, when in excess of hydroxide
The pOH is 6,4.
When the pH is low, the concentration of the hydrogen ions is high. So pH of 3 has a greater concentration of hydrogen ions.
Both hydroxides formed are insoluble in water.Fe(OH)2 is formed at pH=7-9.Fe(OH)3 is formed at pH=2-4.
Sodium hydroxide is a strong base with the chemical formula NaOH. Ammonia water is usually a solution of NH3 and H2O mixed together to form NH4OH,. This is usually the stuff people clean with and is also a strong base. Ammonia (the gas) is just NH3.
No is the answer. Sodium hydroxide is is such a strong alkali that it will 'burn' the cells just like acid does. So it is not found in body. Instead you have sodium bi carbonate. But you have very strong acid in stomach. Hydrochloric acid. Imagine acidity go on increasing ten times as you go from 6 to 5 and 5 to 4. And pH in stomach is 1 to 2. (Why does not stomach is 'not' charred at this pH ?) Pepsin works in high acidic pH only and almost stop working at 5.5 pH. So no question of digestion in sodium hydroxide, which is strong alkali with very high pH. If you lower the pH pepsin starts working again.

This reaction is to be carried out with Sodium hydroxide dissolved in water and Zinc oxide. The product is Sodium Tetrahydroxidozincate(2-) or Simply Sodium Zincate.ZnO + 2 NaOH + H2O ----> Na2Zn(OH)4
The reaction of zinc nitrate and excess sodium hydroxide begins with precipitation of zinc hydroxide ( Zn(OH)2 ), followed by dissolvement after adding excess sodium hydroxide ( 2 OH- ) to formation of zinc aat-ions ( [Zn(OH)4]2- )
Sodium hydroxide 1 N (normal solution) solution has a concentration of39,99710928 g/L (rounded 40 g/L) or 4 g/100 mL sodium hydroxide in water.
1.sodium benzoate
Aluminum hydroxide and Ammonia, Calcium hydroxide and sodium hydroxide. Aluminum hydroxide is used in color fast fabrics and water purification. ammonia is used in cleaners and fertilizer, Calcium hydroxide is used in leather making and mortar and plaster making. sodium hydroxide is used to make soap.
When you put zinc dust in sodium hydroxide solution, sodium zincate and hydrogen are formed. Zn + 2 H2O + 2 NaOH → Na2Zn(OH)4 + H2
precipitated Fe(OH)3 = ferric hydroxide or Fe(OH)4-(aq) = ferrate anion in solution, when in excess of hydroxide
