The field experiment including five treatments [control; urea (150 kg N ha−1); BC (10 t ha−1); urea + BC and urea + BC + UI] was designed following a randomized complete block design (RCBD) with 4 replications. The ‘Pirsabak-2013’ variety of wheat was sown in...
A 12.00-mL sample of an ammonia solution is titrated with 1.899 M HNO3 solution. A total of 19.48 mL of acid is required to reach the equivalence point. What is the molarity of the ammonia solution? A 10.0 mL sample of household ammon...
Would HCl and NaOH generate a salt derived from a weak acid and a weak base? Explain. For a weak acid (e.g. rm CH_3COOH) that is titrated with a strong base (e.g. rm NaOH), what species (ions/molecules) are present in the solution at...
