If the phenolphthalein alkalinity is equal to the total alkalinity then what would be the reason behind alkalinity?a.Bicarbonate ions onlyb.Carbonate ions onlyc.Both, hydroxide and carbonate ionsd.Hydroxide ions onlyClear my choice

If the carbonate ion is only responsible for the alkalinity, thena.The phenolphthalein alkalinity would be greater than half of the methyl orange alkalinityb.The phenolphthalein alkalinity would be equal to half of the methyl orange alkalinityc.The phenolphthalein alkalinity would be equal to the methyl orange alkalinityd.The phenolphthalein alkalinity would be lower than half of the methyl orange alkalinityClear my choice

If a solution of pure water and sodium hydroxide is titrated with H2SO4 for the alkalinity measurement. Then the correct option would be...a.The Phenolphthalein alkalinity will be the total alkalinityb.The Phenolphthalein alkalinity will be the bicarbonate alkalinityc.The Methyl orange alkalinity will be the total alkalinityd.The Phenolphthalein alkalinity will not be the total alkalinity

A water sample was alkaline to both phenolphthalein and methyl orange. 50 mL of the watersample required 18 mL of 0.02 N H2SO4 for phenolphthalein end point and another 6 mLfor complete neutralisation. Describe the type and amount of alkalinity present.a.Alkalinity due to OH– = 240 ppm, Alkalinity due to CO32– = 240 ppmb.Alkalinity due to OH– = 340 ppm, Alkalinity due to CO32– = 140 ppmc.Alkalinity due to OH– = 00 ppm, Alkalinity due to CO32– = 480 ppmd.Alkalinity due to OH– = 24 ppm, Alkalinity due to CO32– = 24 ppm

With respect to the constituents causing alkalinity in water, which of the following situation never arises?

When P is equal to 1/2 M which type of alkaline present in water?a.Carbonate, Bicarbonate and Hydroxide alkalinityb.Only Hydroxide alkalinityc.Only Carbonate alkalinityd.Only Bicarbonate alkalinity
