Yes, all alkalis contain oxygen and hydrogen.
Yes all alkalis have an OH- group, however this is not true for bases.
They all contain acid and bases
No, many alkalis (bases) do not. These include potassium carbonate (Na2CO3), sodium hypochlorite (NaClO), and calcium oxide (CaO).
1. An alkali must contain a metal ion 2. Alkali sometimes can neutralize acid, if it is applied with enough force 3. All alkalis are inedible 4. For an alkali to be found in nature, it must not contain radioactivity 5. Uses of alkalis include tanning leather, cleaning, and scrubbing
All sulphates contain sulphur and oxygen. The sulphate anion has the formulae SO4^(2-) Do not confuse with the sulphite anion , which as the formula SO3^(2-) ; one less oxygen.

No- hydrochloric acid is an acid and is the opposite of an alkali so no alkalis contain it
No, many alkalis (bases) do not. These include potassium carbonate (Na2CO3), sodium hypochlorite (NaClO), and calcium oxide (CaO).
All acids contain H+ but stronger acids contain more than weaker acids. Alkalis contain OH-. In stronger alkalis there is more OH- and in weaker, there is less. This is why pH7 is neutral - the H+ and the OH- form H2O which is a neutral substance.
No, some do not contain oxygen at all
1. An alkali must contain a metal ion 2. Alkali sometimes can neutralize acid, if it is applied with enough force 3. All alkalis are inedible 4. For an alkali to be found in nature, it must not contain radioactivity 5. Uses of alkalis include tanning leather, cleaning, and scrubbing
All alkalis are soluble in water.
All oxides contain oxygen.
As the name 'oxide' suggests, they are all contain 'oxygen'.
sulfur and four oxygen atoms
Yes. All igneous rocks contain oxygen.
