Acids, Bases, and Salts: Indicators, Antacids

Milk in water shows no change. Baking powder in water turns blue. Blue vinegar in water source no change. All the above. When an acidic solution is mixed with a basic solution, they neutralize each other, forming salt and water. Neutral is the solution which does not change the colour of either red or blue Litmus. Phenolphthalein gives pink colour in base type of solution. Red litmus gives blue colour in lemon juice. China rose (gudhal) Beetroot Lichen Blueberries Jamun Both acids and bases change colour of all indicators. If an indicator gives a colour change with an acid it does not give a change with a base. If an indicator changes colour with a base but does not change colour with an acid. Change of colour in an acid and a base depends on the type of indicators. obesity acidity dog bite none of these acidic basic neutral none of these acidic basic neutral none of these Hydrogen ion Hydroxide ion Chloride ion Hydrochloride ion red and blue blue and red pink and colourless colourless and pink an acid and a base an acid and a salt a salt and water a salt and a base add water to acid add acid to water mix acid and water simultaneously add water to acid in a shallow container CO2 SO2 NO2 H2S sulphur dioxide carbon dioxide sodium oxide nitrogen dioxide Vinegar Lime water Turmeric Baking soda Basic Either acidic or basic Either acidic or neutral Either basic or neutral Grapes, lime water Vinegar, soap Curd, milk of magnesia Curd, vinegar Organic matter Quick lime Slaked lime Calamine solution Acids Bases Both (a) and (b) None of these
