Compounds such as alcohols and glucose also contain hydrogen but are not categorised as acids. Describe an Activity to prove it.
Two nails are fitted on a cork and are kept it in a $100\,mL$ beaker. The nails are then connected to the two terminals of a $6\,V$ battery through a bulb and a switch. Some dilute $HCl$ is poured in the beaker and the current is switched on. The same experiment is then performed with glucose solution and alcohol solution.
Why do $HCl$, $HNO_3$, etc., show acidic characters in aqueous solutions while solutions of compounds like alcohol and glucose do not show acidic character ?
Write word equations and then balanced equations for the reaction taking place when -
$(a)$ dilute sulphuric acid reacts with aluminium powder.
$(b)$ dilute hydrochloric acid reacts with iron filings.
What will happen if a solution of sodium hydrocarbonate is heated ? Give the equation of the reaction involved.
A solution turns red litmus blue, its $pH$ is likely to be
A milkman adds a very small amount of baking soda to fresh milk.
$(a)$ Why does he shift the $pH$ of the fresh milk from $6$ to slightly alkaline ?
$(b)$ Why does this milk take a long time to set as curd ?
