WebDec 30, 2024 · Sodium nitrate (NaNO 3) is a neutral salt. It is formed from the strong base (NaOH) and strong acid (HNO 3) reaction. NaNO 3 doesn’t attain any properties of acidic or alkaline on dissolving in an aqueous solution. Sodium nitrate is made from the neutralization of a strong base (NaOH) with a strong acid (HNO 3 ). It has a pH value equal to 7. WebChromium Nitrate is a highly water soluble crystalline Chromium source for uses compatible with nitrates and lower (acidic) pH. All metallic nitrates are inorganic salts of a given metal cation and the nitrate anion.
