HOW STRONG ARE ACID OR BASE SOLUTIONS? We know how acid-base indicators can be used to distinguish between an acid and a base. We have also learnt in the previous section about dilution and decrease in concentration of H+ or OH– ions in solutions. Can we quantitatively find the amount of these ions present in…

What Happens to an Acid or a Base in a Water Solution? Do acids produce ions only in aqueous solution? Let us test this. Activity 2.9 Take about 1g solid NaCl in a clean and dry test tube and set up the apparatus as shown in Fig. 2.4. Add some concentrated sulphuric acid to the…
