Yeh sab acids, khara aur namak... zameen ki kahaani hai. Tez khatta cheez acid hai, jaise nimbu ka ras, jo chot lagne pe jalta hai. Khara cheez jaisi chuna-ka-pani mila hui, jo safai karta hai. Yeh litmus ka kagaz bas batata hai ki pani kaunsi taraf jhuka hai. Mere beej ko ek mitti mein achha lagta hai, doosri mein nahi, waisi hi baat hai.
Par in angrezi powders? Baking soda? Yeh toh khane ka soda hai, jo khara hota hai aur khane ko phulata hai. Woh washing soda, safai karta hai, bada tez khara. Plaster... woh toh puraani deewar ko lagate hain, pani milate hi jam jaata hai, jaise mitti saat mein ghee mila kar jamti hai. Inmein kya khatta-khara? Yeh sab ghar ke nuskhe hain, chemistry nahi.
